The document lists over 100 methods that a Plone ATFolder object has in the Zope 3 Component Architecture. It appears to be listing all possible methods and attributes of an ATFolder to demonstrate the complexity and capabilities provided to components through the Zope 3 framework. The extensive list shows how components can be developed to have a wide range of customizable behaviors and functionality through the use of methods in their class definitions.
This document provides an introduction to JavaScript and jQuery. It defines JavaScript as a scripting language used to create dynamic and interactive web pages and applications. It resides in the browser rather than on the server. JavaScript uses functions to organize code into well-defined, reusable tasks. Functions are executed when events occur or when called from other scripts. The document also defines jQuery as a JavaScript library that simplifies client-side scripting with HTML through its selector engine and methods. jQuery code is linked in the page head or an external file below CSS but above other scripts.

The document describes the development of a web application by a student group. It details validation of the application's HTML and CSS code using the W3C Markup Validation Service and CSS Validation Service. The HTML validation returned 12 errors related to duplicate IDs, missing required attributes, and invalid element placement. The CSS validation returned 10 errors related to invalid syntax, missing units, and files not being found.
This chapter introduces XHTML and covers:
- The transition from HTML to XHTML and XML syntax requirements
- The anatomy of a web page including head, body, and DTD sections
- Common inline and block-level tags for formatting text and elements
- Special characters and how to display them
- Creating hyperlinks within and between pages using absolute and relative linking
The document provides an overview of HTML elements and tags for basic webpage structure and formatting. It discusses the <html>, <head>, <body> tags and their uses. It also covers common text formatting tags (<p>, <h1>-<h6>), lists (<ul>, <ol>, <li>), links (<a>), images (<img>), and the differences between relative and absolute links. The document is intended as an introduction to basic HTML tags and elements for building webpage structure.
HTML5 will be the new standard for HTML, XHTML, and the HTML DOM.
The previous version of HTML came in 1999. The web has changed a lot since then.
HTML5 is still a work in progress. However, most modern browsers have some HTML5 support.
The document discusses various web application security vulnerabilities such as hidden field manipulation, parameter tampering, cross-site scripting, and SQL injection. It provides examples of how attackers can exploit these vulnerabilities and recommendations for developers on how to prevent attacks, including sanitizing user input, encrypting cookies, and validating parameters.
The document compares three local storage mechanisms for the front end: Manifest, Web SQL Database, and LocalStorage.
Manifest allows caching static files but is difficult to debug and modify. Web SQL Database provides a full SQLite database but has increased learning costs and may be deprecated. LocalStorage is lightweight, fast, easy to use, and widely supported but has quota limits and lacks advanced features.
The document outlines the course objectives and topics that will be covered in an XHTML review course, including creating tables, forms, image maps, and optimizing pages for search engines. The topics are introduced and basic syntax for implementing tables, forms, and image maps in XHTML are demonstrated through code examples.
The document provides an overview of HTML5, including new features such as video playback, drag-and-drop, local storage and geolocation. It discusses HTML5 syntax, elements, attributes, forms, and events. Key points include HTML5 being the latest version that incorporates features previously requiring plugins, improved form handling, and new semantic elements like <header> and <section>. Browser support for HTML5 is good among modern browsers.
The document provides an overview of HTML5, including new features such as video playback, drag-and-drop, local storage, web sockets, and more. It discusses browser support for HTML5, new semantic elements like <header> and <footer>, forms improvements, and the updated syntax of HTML5 which is more flexible than previous standards. The document is a tutorial for HTML5 from TutorialsPoint that aims to give readers a good understanding of the latest capabilities and structure of HTML5.
The document provides an overview of HTML elements and tags. It discusses the anatomy of elements, including tags, content, and attributes. Common block elements (like <p> and <div>) and inline elements (like <img> and <a>) are described. The document also covers important tags like <a> for links, <table> for tables, and <form> for forms. It explains how to properly structure these elements and includes examples of proper syntax and usage. Key concepts covered include relative vs. absolute links, the <index> file, using colspan to span table columns, and required form attributes like "action" and "name".
The document discusses HTML, XHTML, CSS, and markup elements. It provides explanations of key concepts:
- HTML is the language used to write websites and stands for Hypertext Markup Language. It uses elements, attributes, and values to structure and style web pages.
- CSS allows setting styles like fonts and colors for HTML elements in one central location to apply across pages. CSS enhances HTML but is separate from it.
- XHTML elements, attributes, and empty elements are used to identify, describe and structure different parts of a web page. Elements can contain other elements in a nested hierarchy.
This document discusses various topics related to web development including:
- The difference between static and dynamic web content. Most websites contain both.
- HTML is the markup language used to describe web pages and uses tags to describe different content.
- CSS is used to define styles and presentation rules for HTML elements. CSS rules are defined with selectors and declarations.
- JavaScript can be used to add interactivity to HTML pages and is usually embedded directly into web pages.
- Events trigger JavaScript code to run, such as when a user clicks an element or submits a form. Event handlers define the code that runs in response to events.
The document discusses various topics related to web development including XHTML, CSS, and JavaScript. It provides definitions and explanations of XHTML, CSS, JavaScript, and the differences between HTML and XHTML. It also covers common issues with supporting older browsers like IE6 and strategies for overcoming those issues such as using frameworks to simplify tasks like DOM manipulation and event handling.
The document discusses best practices for semantic markup. It provides guidance on using semantic elements like <div>, <span>, <a>, <img>, lists, forms, and specific semantic elements properly. It also covers topics like accessibility, maintainability, validation, HTML vs XHTML, and keeping up with HTML5 and browser standards. The document emphasizes using semantic markup that encodes meaning, is device-interoperable, and accessible to all users.
The document discusses the reasons for using HTML5, including backwards compatibility, richer media capabilities, and more semantic tags. It provides examples of simplified HTML5 code compared to older HTML versions. Key points are made around proper HTML5 syntax like using boolean attributes without values and updated tag meanings like the <b> tag indicating stylistic offset instead of extra importance.
This document provides an overview of HTML elements and tags. It discusses the basic HTML page structure including <html>, <head>, and <body> tags. It also covers common text formatting tags, links, images, lists, and more. The document emphasizes that HTML provides semantic structure and meaning to content through appropriate tag usage. It concludes with a brief discussion of relative vs. absolute links and FTP for transferring files to a server.
This document provides an overview of HTML (Hypertext Markup Language) including:
- HTML uses tags to specify formatting and layout of text on web pages
- Common HTML elements include headings, paragraphs, links, and empty elements
- The <head> element contains metadata like the <title> and <meta> tags
- Attributes provide additional information about HTML elements
- Special characters are encoded using character entities to be properly displayed in HTML
The document discusses the key components of HTML markup, including elements, character data types, character and entity references, and the document type declaration. It provides an example of a basic "Hello World" HTML page and explains the structure and purpose of the HTML, head, title, and body tags. It also defines common HTML elements like headings, paragraphs, line breaks, and comments.
This document provides an overview of Windows Presentation Foundation (WPF). WPF introduces a new display engine based on DirectX, allowing for resolution independence, vector graphics, and leveraging of modern GPU hardware. It also integrates multimedia and provides a new .NET-based development model separating UI from logic using XAML. Key topics covered include XAML, layout panels, controls, styles/templates, data binding, and commands. WPF allows richer user interfaces, collaboration between designers and developers, and interoperability with existing code.
Markup provides information about document structure and presentation. It includes start and closing tags like <p> and </p>. HTML is a markup language used to build web pages and includes elements like <head> and <body>. It has a defined structure with tags nested properly. HTML documents are text files with a .html extension.
The document describes the development of a web application by a student group.

The element named above was found in a context where it is not allowed. This could
mean that you have incorrectly nested elements -- such as a "style" element in the
"body" section instead of inside "head" -- or two elements that overlap (which is not
allowed).

One common cause for this error is the use of XHTML syntax in HTML documents. Due
to HTML's rules of implicitly closed elements, this error can create cascading effects. For
instance, using XHTML's "self-closing" tags for "meta" and "link" in the "head" section of
a HTML document may cause the parser to infer the end of the "head" section and the
beginning of the "body" section (where "link" and "meta" are not allowed; hence the
reported error).

The attribute given above is required for an element that you've used, but you have omitted
it. For instance, in most HTML and XHTML document types the "type" attribute is
required on the "script" element and the "alt" attribute is required for the "img" element.
Typical values for type are type="text/css" for <style> and type="text/javascript"
for <script> .

You have used the attribute named above in your document, but the document type you
are using does not support that attribute for this element. This error is often caused by
incorrect use of the "Strict" document type with a document that uses frames (e.g. you
must use the "Transitional" document type to get the "target" attribute), or by using
vendor proprietary extensions such as "marginheight" (this is usually fixed by using CSS
to achieve the desired effect instead).
This error may also result if the element itself is not supported in the document type you
are using, as an undefined element will have no supported attributes; in this case, see the
element-undefined error message for further information.
How to fix: check the spelling and case of the element and attribute, (Remember XHTML
is all lower-case) and/or check that they are both allowed in the chosen document type,
