HTML5, CSS, JavaScript Style guide and coding conventionsKnoldus Inc.
Coding conventions are style guidelines for any programming language. As, we are growing ourselves rapidly in learning new technology, the need for learning of the coding standards and conventions for the same language also arises.
So, here let us try to learn some coding guidelines for few frontend languages.
CSS stands for Cascading Style Sheets
Styles define how to display HTML elements
External Style Sheets can save a lot of work
Styles are normally saved in external .css files. External style sheets enable you to change the appearance and layout of all the pages in a Web site, just by editing one single file!
JavaScript is a client-side scripting language that allows web pages to become interactive and dynamic. It can update and modify the content of an HTML page without needing to reload the page. JavaScript code can be embedded directly in HTML pages or placed in separate .js files. Common uses of JavaScript include validating form input, detecting the visitor's browser, creating cookies, and adding interactivity to HTML elements like buttons and links.
This is the CSS Tutorial for Beginners that teach the basics of CSS. This tutorial will show the basic structure of a CSS style and will show 3 different methods to apply styles.
The Document Object Model (DOM) is a standard for representing and interacting with objects in HTML, XML and SVG documents. It defines the logical structure of documents and the way a document is accessed and manipulated. The DOM represents the document as nodes and objects, which can be manipulated programmatically by JavaScript to change the document structure, style and content. It allows dynamic access to and manipulation of page content that is useful for building interactive web applications. The DOM specification is developed by the W3C and provides a platform- and language-neutral interface that can be used across different web technologies.
CSS (Cascading Style Sheets) is a stylesheet language used to describe the presentation of a document written in HTML or XML. CSS saves lots of work as formatting elements only need to be applied to one CSS file rather than individually formatting every HTML page. CSS rules consist of selectors that point to the HTML element to style paired with a declaration block containing CSS properties and values to determine how that element will look. Common CSS properties include those to control text formatting, background effects, borders, lists, links and positioning.
HTML allows users to create web pages. It uses tags to format text, add images and other multimedia, and create hyperlinks. Some key points:
- HTML was created by Tim Berners-Lee in 1989 and standardized in 1997.
- It uses tags enclosed in angle brackets like <p> to format text into paragraphs.
- Common tags include <h1> for main headings, <img> to add images, and <a> for hyperlinks.
- Tables, lists, and forms can be added using <table>, <ul>/<ol>, and <form> tags.
- HTML pages are plain text files that can be viewed on any browser.
HTML structures web documents and defines the semantics, or meaning, of content. CSS handles presentation and styling. HTML uses tags to define headings, paragraphs, lists, links and other content. CSS allows styling of elements using selectors, properties and values. External CSS files allow separation of concerns and reuse of styles across pages.

This document provides an overview of Cascading Style Sheets (CSS) including:
- CSS handles the look and feel of web pages by controlling colors, fonts, spacing, layouts, backgrounds and more.
- CSS versions include CSS1 for basic formatting, CSS2 for media styles and positioning, and CSS3 for new features like colors and transforms.
- There are three ways to apply stylesheets: inline with HTML tags, internally within <style> tags, and externally with <link> tags.
- The Style Builder in Microsoft allows applying styles through a dialog box with options for fonts, backgrounds, text, positioning, and other properties. Basic CSS syntax uses selectors and properties to
1. CSS (Cascading Style Sheets) is a language used to define the style and layout of web pages. CSS can be applied internally, inline, or through external style sheets.
2. There are different types of CSS selectors including tag selectors, ID selectors, and class selectors that allow styles to be applied to specific HTML elements. Common CSS properties define colors, fonts, spacing, and layout.
3. CSS3 introduces newer specifications like rounded corners, shadows, gradients, transitions, and transformations that expand on the original CSS standards. Features like custom fonts, multi-column layout, flexible box and grid layouts add additional styling capabilities.
The document discusses various aspects of HTML5 including its history, new elements, offline storage capabilities, and responsive web design. It provides information on HTML, CSS, JavaScript and how they make up the three layers of web design. It also summarizes the roles of different standards organizations and differences between HTML5 and the HTML living standard.
Audio and video became first citizens on the Web with HTML5 the same way that other media types like images did in the past.
With the coming additions to the APIs you will be able to read and write raw data to audio files (Audio Data API) or manipulate captions in vídeos (Timed Track API).
CSS can be used to specify styles for different media types using media queries. The most common media types are all, screen, and print. There are five methods for applying styles to different media - using <link> tags, <?xml-stylesheet?> tags, @import rules, and @media rules within CSS. @media rules allow applying different styles for different media types from a single CSS file. This improves performance and maintenance by reducing server hits and links needed in HTML.
The document discusses CSS selectors and specificity. It provides examples of different types of selectors including contextual selectors that specify an element's context or position in relation to other elements, and attribute selectors that target elements based on attributes and values. The document also explains how to calculate a CSS rule's specificity and which rule will be applied if there are conflicts. Visual examples are used to demonstrate different contextual selectors and the elements they would select.
This document provides an overview of key features in Sightly, an HTML templating language used in Adobe Experience Manager (AEM):
- It describes Sightly statements like data-sly-use, data-sly-attribute, data-sly-element, and data-sly-resource that allow manipulating elements, attributes, and including resources.
- Expression options like @context, @format, @join, and @i18n that control output are also covered.
- URI manipulation using options like @scheme, @domain, @path, @query, and @fragment is explained.

UNIT 6: BCS-AWD-6 Advanced CSS
This document provides an introduction to CSS (Cascading Style Sheets), including what CSS is, why it is used, its history and syntax. It describes CSS selectors, properties, and different methods of attaching style definitions. It also covers the CSS box model and properties for styling text, links, lists, backgrounds, borders, margins and paddings.
CSS inheritance allows descendant elements to inherit certain CSS properties from their ancestor elements. This helps reduce the amount of CSS code needed and makes styling easier. Key properties like color, font-size, and font-family are inherited by default. Font-size inheritance works by inheriting the calculated pixel value rather than the actual percentage or EM value. Understanding inheritance is important for efficiently writing CSS with less code.

This document introduces CSS (Cascading Style Sheets) and provides examples of how to use CSS to style HTML elements. CSS allows separation of document structure (HTML) from presentation (CSS). There are three ways to associate CSS with HTML - external CSS files linked via <link>, internal <style> sections, or inline styles via the style attribute. CSS selectors target elements by tag name, class, ID, or context. Classes and IDs allow targeting groups or individual elements. CSS rules define styles using properties and values within curly braces. This allows consistent styling across pages by changing a single CSS file.
The document outlines an agenda and lesson plan for teaching CSS. The agenda includes warm up revision, a teacher presentation on CSS, a video on CSS selectors, practical work in pairs to create a web page using CSS, a question and answer session, reflection, and assigning homework. The lesson plan covers CSS terminology, adding style using cascading style sheets, internal and external styles, CSS syntax, selectors like type, class, and ID, properties for boxes, fonts and text, and linking stylesheets. Resources for further practice are provided. The homework assignment asks students to create a web page using HTML and CSS based on a rubric.

Why Apache Kafka Clusters Are Like Galaxies (And Other Cosmic Kafka Quandarie...Paul Brebner
Closing talk for the Performance Engineering track at Community Over Code EU (Bratislava, Slovakia, June 5 2024) https://eu.communityovercode.org/sessions/2024/why-apache-kafka-clusters-are-like-galaxies-and-other-cosmic-kafka-quandaries-explored/ Instaclustr (now part of NetApp) manages 100s of Apache Kafka clusters of many different sizes, for a variety of use cases and customers. For the last 7 years I’ve been focused outwardly on exploring Kafka application development challenges, but recently I decided to look inward and see what I could discover about the performance, scalability and resource characteristics of the Kafka clusters themselves. Using a suite of Performance Engineering techniques, I will reveal some surprising discoveries about cosmic Kafka mysteries in our data centres, related to: cluster sizes and distribution (using Zipf’s Law), horizontal vs. vertical scalability, and predicting Kafka performance using metrics, modelling and regression techniques. These insights are relevant to Kafka developers and operators.

HTML and CSS Coding Standards

designersaajan@gmail.com, Kathmandu ,Nepal.
Coding Standards
1.Comments on Code
Commented on Markup
<!-- header -->
Text information is separated from the tag by a “space ”. No additional symbols are
required.
This form is incorrect:
<!-- header ///// -->
<!-- *** header *** -->
You should comment:
1. main markup blocks (header, footer etc.)
2. main semantic blocks and elements (logo, navigation, breadcrumbs, article
etc.}
3. main functional blocks and elements (sub-navigation, popup, search contact
form etc.}
If it is impossible to find a semantic title, you can use a block heading or class as a title:
<!-- welcome block -->
or
<!-- block title -->
An example of the correct HTML comment:
<!-- main -->
<!-- header -->
<!-- navigation -->
<!-- content -->
Commented on CSS
/* article */
2. 2 Markup and CSS Code Standardization.| Prepared by: Saajan Maharjan,
designersaajan@gmail.com, Kathmandu ,Nepal.
Text information is separated by a "space". No other additional symbols are required.
There is no need in closing comments. Just mark the beginning of the block styles.
The following form is incorrect:
/* ##### article ##### */
/* --== article ==-- */
Initial reset of elements (even if it is very small) should be commented as /* General
reset */.
Comments in CSS must correspond the comments in HTML.
If after "General reset" there follows the declaration of all main blocks, it is mentioned as
/* General settings */:
/* General settings */
#header{...}
#content{...}
#sidebar{...}
#footer{...}
An example of the correct CSS comment:
/* main */
/* header */
/* navigation */
/* content */
File Naming and Organization
The following example file structure should be used for static resources (framework-
specific conventions take precedence):
/css
/reset.css
/main.css
/ie.css
/images
/btn-submit.png
/btn-submit-SOURCE.psd
/js

Best Practices
Use a global reset. A global reset helps create more consistent presentation
across browsers.
Use sprites for all rollover/active states. CSS sprites prevent unwanted image
flicker on rollover. CSS sprites also reduce the total number of HTTP requests.
Use as few browser-specific styles as possible. If needed, browser-specific
stylesheets or page classes (http://paulirish.com/2008/conditional-stylesheets-vs-
css-hacks-answer-neither/) should be used instead of putting CSS hacks in the
main stylesheet.
Validate CSS.
Optimization Code and file
1. Use shorthand
If you’re not already writing in shorthand, you’re late to the party. But fortunately, this
party never ends. Using shorthand properties is the single easiest practice you can do to
cut down your code (and coding time). There’s no better time than the present to start
this efficient coding practice, or to review it.
Margin, border, padding, background, font, list-style, and even outline are all properties
that allow shorthand (and that’s not even an extensive list!).
CSS Shorthand means that instead of using different declarations for related
properties…
p { margin-top: 10px;
margin-right: 20px;
margin-bottom: 30px;
margin-left: 40px; }
… you may use shorthand properties to combine those values like so:
p { margin: 10px 20px 30px 40px; }
2. Axe the Hacks
we know that using conditional comments to serve hacks correctional declarations for IE6 and
IE7 is an accepted practice, even recommended by the Microsoft IE development team. Using
conditional comments to serve IE-specific CSS rules has the added benefit of serving a cleaner,
and therefore smaller, default CSS file to more standards-compliant browsers, while only those
browsers that need the hackery daiquri (i.e. IE) will download the additional page weight.
4. 4 Markup and CSS Code Standardization.| Prepared by: Saajan Maharjan,
designersaajan@gmail.com, Kathmandu ,Nepal.
Here’s how to use conditional comments to serve styles only to Internet Explorer 6:
<!--[if IE 6]>
<link rel="stylesheet" type="text/css" href="ie6.css">
<![endif]-->
3.Optimize the file
Optimize the jpg and png
PNG is useful because it's the only widely supported format that can store partially
transparent images. The format uses compression, but the files can still be large. Use
PNGauntlet and to optimize the jpeg file use the jpegmini tools to shrink images for your
apps and sites. It will use less bandwidth and load faster.
PNG optimize tool
4.Optimize the js code and css code
Use the single file for the js and css file as follows the all.css for all the css code and
jquery.js for all the customize jquery code.
5. 5 Markup and CSS Code Standardization.| Prepared by: Saajan Maharjan,
designersaajan@gmail.com, Kathmandu ,Nepal.
5. Use whitespace wisely
Whitespace, including spaces, tabs, and extra line breaks, is important for readability for
CSS code. However, whitespace does add, however miniscule it may be, to page
weight. Every space, line-break, and tab you can eliminate is like having one less
character. Always favor for single line formatting option without tabs. Eg. As follows
Multi-line formatting, double-spaced, indented code
Example
.code-standard{
background:transparent;
width:205px;
border:none;
overflow:hidden;
cursor:pointer;
}
Single-line formatting, single-spaced, no indentation
Example
.code-
standard{background:transparent;width:205px;border:none;overflow:hidden;cursor:poi
nter;}
6.Tidying up your HTML tags with indentation
You may already be finding that it is a bit hard to look at the HTML in your editor and to
understand it. Part of this will be the layout (part will be that HTML is confusing for a
while).
To help you to see the structure of a Web page's HTML it is best to indent the code. This
means putting tabs into your HTML. Remember that these tabs will not be shown on the
6. 6 Markup and CSS Code Standardization.| Prepared by: Saajan Maharjan,
designersaajan@gmail.com, Kathmandu ,Nepal.
Web page (extra spaces and tabs are ignored by browsers the same way as line
breaks).
The idea is to put a tab before each line of code which is inside another tag. This makes
more sense if you see it. This is what you have in your file so far but properly indented:
Example

What Beautiful HTML Code Looks Like

6.Use HTML and CSS Validator
Why Code validation for?
Validation as a debugging tool
Validation as a future-proof quality check
Validation eases maintenance
Validation helps teach good practices
Validation is a sign of professionalism
For Markup validation use
http://validator.w3.org/
8. 8 Markup and CSS Code Standardization.| Prepared by: Saajan Maharjan,
designersaajan@gmail.com, Kathmandu ,Nepal.
For CSS validation use

Naming and accessibility
logo.gif – main logo of the page
logo.gif...logo10.gif – logos list
The logo image can be named after the owner's company
Examples: puma.gif, adidas.gif, microsoft.gif, contex.gif, durex.gif
sponsor-logo1.gif (partner-logo1.gif – depending on the logo list title) – sponsors'
logos can also be named based on the companies' names: adidas.gif,
w3ukraine.gif etc, but please follow a certain logical order f.ex. there must be no
adidas.gif and logo10.gif in one list.
btn-go.gif, btn-submit.gif, btn-name.gif – for form elements or for big block links.
text-sometext.gif – for text replacement (titles).
bg-body.gif, bg-footer.gif – for background images.
img1.gif, img2.gif, item1.gif, item2.gif – for product lists, or non-systematized
images.
ico-email.gif, ico-star.gif, flag-ua.gif, flag-uk.gif – for icons.
separator.gif, divider.gif – if the image is being used as a separator
bullet.gif(bullet-green.gif, bullet1.gif, bullet5.gif, bullet-small.gif, bullet-medium.gif)
– if the image is being used for list styling.
Variants of naming: arrow, arrow-red, arrow-small, arrow-left etc.
Image title must always be meaningful.
Do not write anything into “alt” attribute to preserve images accessibility.
We only write data into “alt” attribute when there is a demand of Web Accessibility,
SEO or Section508. “Alt” attribute content has to reflect the content or meaning of the
image. If it is impossible/difficult to write the content correctly, then put «image
description» in the “alt”
If Web Accessibility, SEO or Section508 are NOT required then you can set 'image
description' for all images.
If the image is meaningless (simply for design purposes) you don't need to set “alt”
attribute.
