LESS is a CSS pre-processor that extends CSS by adding features like variables, mixins, functions and nested rules. This allows CSS to be more maintainable, themeable and extendable. The document outlines key LESS features like variables, operations, functions, mixins, loops and compiling LESS to CSS. It provides examples of how each feature can be used.
An overview of the CSS preprocessor LESS.
Including code samples for creating mixins, variables, math, colors, patterns, guards, scope, and namespaces.
The Cascade, Grids, Headings, and Selectors from an OOCSS Perspective, Ajax ...Nicole Sullivan
The cascade is a poker game, but we've been playing our cards all wrong. Here Nicole suggests we stop trying to play to win to prevent code bloat, and simplify the cascade, using the order of the rulesets to allow overrides.

LESS is a dynamic stylesheet language. It extends CSS with dynamic behavior such as variables, mixins, operations and functions. Imagine being able to define a color one time and then use it in multiple places. To be able to say, "Take that background color and have it darken by 20% when I hover over it." Imagine being able to use rounded corners without needing to remember and write the styles for all the different browsers, to be able to create gradients in CSS by just telling it the colors you want to use.
This session will introduce you to LESS, show you how to use it, and walk you through how to set up the software to use it. Since this is an extension of CSS, you should know some CSS. The examples will be taken from Bootstrap and Joomla JUI so having basic knowledge of that is helpful.

CSS in React is a talk I gave at the ReactJS San Francisco Bay Area meetup yesterday. It covers viable options for implementing CSS in JavaScript React components and the good and bad parts of various solutions including Radium, react-css-modules, styled components, combined with Sass, Webpack, Babel, and ES6.
It also includes a github repo https://github.com/joeshub/css-in-react where you can run all the examples locally
Today we have CSS specifications for animation and transitions, complex layout, custom properties and much more. In addition to the breadth of modern CSS specifications, our evergreen, auto-updating browsers sneak in new features with every release.
In this talk, I’ll be taking a look at some of the things that CSS is capable of, some of which you might think you need a JavaScript framework or at least a pre-processor to achieve.
From Nicole's presentation at the CSS Summit. This is brand new research regarding efficient CSS selector design. Practicing the rules outlined here will make your CSS lean, your site fast, and your maintenance minimal. A beautiful combination for people concerned with building performance into their sites.

Big Data Day LA 2015 - Compiling DSLs for Diverse Execution Environments by Z...Data Con LA
Data transformation has traditionally required expertise in specialized data platforms and typically been restricted to the domain of IT. A domain specific language (DSL) separates the user’s intent from a specific implementation, while maintaining expressivity. A user interface can be used to produce these expressions, in the form of suggestions, without requiring the user to manually write code. This higher level interaction, aided by transformation previews and suggestion ranking allows domain experts such as data scientists and business analysts to wrangle data while leveraging the optimal processing framework for the data at hand.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

Outline
3. ● What is LESS?
○ Less is a CSS pre-processor, meaning that it
extends the CSS language, adding features that
allow variables, mixins, functions and many other
techniques that allow you to make CSS that is
more maintainable, themeable and extendible.
● Usage Development Mode
Introduction
LESS
<link rel="stylesheet/less" type="text/css" href="styles.less" />
Library
<script src="less.js" type="text/javascript"></script>
8. ● Variable Names
Variables (5/7)
// Variable
@fnord: "I am fnord.";
@var: "fnord";
// Usage
.text {
content: @@var;
}
LESS
// Outputs
.text {
content: "I am fnord.";
}
CSS (outputs)
9. ● Lazy Loading
○ Variables are lazy loaded and do not have to be
declared before being used.
Variables (6/7)
.lazy-eval {
width: @var;
}
@var: @a;
@a: 9%;
LESS
.lazy-eval-scope {
width: 9%;
}
CSS (outputs)
10. ● @import
○ Import styles from other style sheets
Variables (7/7)
@import "foo"; // foo.less is imported
@import "foo.less"; // foo.less is imported
@import "foo.php"; // foo.php imported as a less file
@import "foo.css"; // statement left in place, as-is
13. ● Example 1
Extend (1/2)
nav ul {
&:extend(.inline);
background: blue;
}
.inline {
color: red;
}
LESS
nav ul {
background: blue;
}
.inline, nav ul {
color: red;
}
CSS (outputs)
14. ● Example 2
Extend (2/2)
nav ul:extend(.inline) {
background: blue;
}
.inline {
color: red;
}
LESS
nav ul {
background: blue;
}
.inline, nav ul {
color: red;
}
CSS (outputs)
26. ● Conditional mixins
○ Additionally, the default function may be used
to make a mixin match depending on other mixing
matches, and you may use it to create
"conditional mixins" similar to else or default
statements (of if and case structures
respectively):
Mixin Guards (2/3)
.mixin (@a) when (@a > 0) { ... }
.mixin (@a) when (default()) { ... } // apply when @a <= 0
27. ● Guard comparison operators
○ > : greater than
○ >= : greater than or equal to
○ = : equal to
○ =< : little than or equal to
○ < : little than
● Guard logical operators
○ and : and logical operator
○ , : or logical operator
● Type checking functions
○ iscolor(), isnumber, isstring, iskeyword, isurl,
ispixel, ispercentage, isem, isunit
Mixin Guards (3/3)
28. ● Example 1
Loops (1/2)
.loop(@counter) when (@counter > 0) {
.loop((@counter - 1));
width: (10px * @counter);
}
div {
.loop(5);
}
div {
width: 10px;
width: 20px;
width: 30px;
width: 40px;
width: 50px;
}
