Object Oriented CSS

We keep thinking we can write better CSS if we just try harder, that the next site will be clean and stay that way. This presentation shows that in fact, messy CSS is the direct result of our worst best-practices. We need to reexamine those assumptions with an eye to practicality and scalability as well as accessibility, standards, and fabulous design.

This document provides an introduction to JavaScript and jQuery. It covers basic JavaScript concepts like variables, functions, conditional statements, and user input/output.

It also covers JavaScript functions, returning values from functions, and printing pages. The document describes JavaScript strings and array objects, and their associated methods. Finally, it discusses different types of errors in JavaScript like syntax errors, runtime errors, and logical errors.

The document provides an agenda for a workshop on HTML, CSS, and putting them together. It covers HTML topics like semantic tags, comments, and best practices. It then discusses CSS topics such as IDs vs classes, floats, shorthand, and putting HTML and CSS together with project structure and layouts. The workshop aims to give an introduction to HTML, CSS, and how to structure websites using these languages.

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.

jQuery is a popular JavaScript library that makes HTML document traversal and manipulation, event handling, animation, and Ajax interactions more simple. It works across browsers and allows developers to write less code using its easy-to-use API. The document discusses how jQuery works, including how to launch code on document ready, add and remove HTML classes, and use callbacks and functions when passing arguments to other functions.

This document discusses responsive web design using CSS3 media queries. It begins with an introduction to media queries and their syntax for modifying CSS based on screen width. It then covers examples of adapting layouts, images, and other design elements for different screen sizes. Finally, it addresses techniques for supporting older browsers that do not support media queries, such as using conditional comments or JavaScript libraries.

This document provides an overview of HTML including: - A brief history of HTML from its creation in 1989 to modern standards. - An explanation of basic HTML tags for formatting text, creating links, inserting images, and organizing content using lists, tables, and frames. - Descriptions of common HTML attributes for further customizing tags. - Recommendations for the essential tools and resources needed to get started with HTML.

The document discusses React patterns and hooks. It covers topics like inheritance, composition, mixins, render props, higher order components (HOCs), and React hooks. Some key points: - Inheritance and composition are approaches to code reuse in object-oriented programming. React uses composition over inheritance. - Mixins were introduced in 2015 for code reuse but are now deprecated due to issues. Render props and HOCs are preferred patterns. - Render props and HOCs allow code and state to be shared across components. Render props have fewer levels of nesting while HOCs are better for applying multiple concerns. - Hooks were introduced to overcome class component limitations and support functional components with local state and lif

This document introduces Sass (Syntactically Awesome Style Sheets), a CSS preprocessor. Sass allows writing clean CSS in a programming construct rather than static rules, reducing repetition and creating more manageable stylesheets. It features variables, nesting, mixins, partials, and inheritance. Installing Sass involves downloading Ruby and using the gem install command. Key benefits of Sass include writing cleaner CSS, faster development time, and programmatic features like variables and nesting.

This PPT is about my best friends, HTML, CSS and JS. Here I am just talk/show few features of them. all three combined make our web site more powerful in this WWW world.

This document provides an introduction to JavaScript and discusses its uses, places to insert code, variables, operators, and the Document Object Model (DOM). JavaScript is an object-based scripting language used mainly for client-side validation, dynamic drop-downs, displaying data and time, and pop-ups. Code can be inserted between HTML tags, in external JavaScript files, or between the <head> tags. The DOM represents the HTML document as a tree structure that can be modified.

JavaScript is a scripting language that allows adding interactivity to HTML pages. It can be used for client-side form validation and integration with user plugins. JavaScript is case-sensitive and allows variables, functions, conditional statements, and objects. Common uses include pop-up boxes, event handling, and cookies.

This document introduces React, describing it as a JavaScript library for building user interfaces by rendering components rather than mutating the DOM directly. It discusses how React uses a virtual DOM for fast re-rendering, building components instead of templates, and the use of JSX syntax to write HTML-like code. Components have state and props, and the whole app re-renders when state changes to guarantee updates.

This is the first half of a presentation I gave at Squares Conference 2015 where I provided a brief introduction to React JS, then did live coding for 20 minutes to show more of the specifics of usage. Your milage may vary as the live code part was where the bulk of the teaching happened!

You've got a sneaking suspicion that design impacts performance. What next? Your engineers know nothing about design and your designers know nothing about performance. How can you get everyone on the same page? Which design flaws must you absolutely avoid? How do engineers slow designs with poor CSS? This presentation covers the best practices in design and OO CSS for fast, maintainable sites. * Abstraction * Flexibility * Grids * Location dependent styles Velocity Conference, 2009

Almost exactly the same slides as for BDConf and Mobilism 2012, but some might appreciate having the actual slides from this event.

It outlines several principles of OOCSS including creating reusable CSS components, separating container and content rules, extending objects by applying multiple classes, avoiding location-dependent styles, and separating structure from skin. Examples are provided to illustrate these concepts. The goal of OOCSS is to write more modular, predictable and maintainable CSS code.

The document discusses the advantages and disadvantages of developing applications for the iPhone using web development versus using the iPhone SDK. Some key advantages of web development are simplicity, dynamism from being able to easily update functionality, and global reach from being part of the web. Some advantages of using the iPhone SDK include greater depth of functionality by having deeper access to device features and better performance from being native code. The document considers factors for each approach for different types of iPhone applications.

The document discusses common mistakes in SharePoint branding: 1. Jumping into code too soon without understanding SharePoint patterns and structures. 2. Ignoring non-visible parts of the SharePoint platform that can impact branding work. 3. Coding branding solutions for personal preferences rather than the needs of end users.

Lightning Web Components (LWC) is a new programming model built on modern web standards that provides enhanced productivity, performance, and compatibility. LWC uses ES6+, Custom Elements, and Shadow DOM for a faster and more standards-based experience. It runs alongside existing Lightning components and can be used via clicks or code. LWC takes advantage of advances in web standards like the W3C and ECMAScript to provide a more performant and transferable skills framework compared to prior Lightning frameworks.

JavaScript is a lightweight, interpreted programming language that is used for client-side web development. It was originally introduced in 1995 to make web pages more interactive and has since expanded to server-side applications through Node.js. Some best practices for JavaScript include using meaningful variable names, writing narrative code, avoiding polluting the global namespace, using strict mode, isolating DOM access, following common patterns like the module pattern, and progressively enhancing functionality while degrading gracefully without JavaScript.

This document provides an introduction to understanding the Document Object Model (DOM). It discusses what the DOM is, how it represents XML documents as a tree structure of nodes, and how the DOM specifications have evolved over time to support additional XML features. The document also outlines what tools are needed to run the Java examples provided, and introduces the author and conventions used in the tutorial.

A reflection on career and community. A call to follow your heart rather than some abstract notion of success.

Refactoring Trulia’s UI with SASS, OOCSS, and handlebars. My slides from jsconf 2013. Lot's of yummy details about the performance improvements we were able to make.

The JavaScript community is one of the most vibrant and fun groups I've ever been lucky enough to be a part of. Like any vibrant community, sometimes people don't play nicely. In this session, I will discuss what it has been like to be shy *and* be on twitter, mailing lists, and open source. I'll talk about my experiences consulting on massive CSS overhauls, and ways to defeat trolls -- including your own inner troll! I'll also share a timing attack for your brain that might just surprise you.

Let’s admit it, the tools for writing CSS aren’t very advanced. For the most part, the people who write tools don’t know about CSS and the people who know about CSS don’t write tools. Quite a conundrum! In this session, you’ll learn about good tools that can make development faster and maintenance easier. We’ll also talk a bit about where we can go from here. What tools do we need as sites are becoming more and more complex? We need to get beyond tools whose primary goal is to avoid hand-coding and realize that, as our techniques for writing CSS become more powerful, our tools can too! Session will include: * Validators * Preprocessors * Finding dead rules * Linting * CSS3 gradient tools * Performance measurement tools * Unit testing

Nicole Sullivan and Stoyan Stefanov discuss their work optimizing CSS at Facebook and Yahoo!, As well as the state of CSS optimizations in the Alexa Top 1000 websites. What a mess! From Velocity Conference and Texas-Javascript.

From Nicole's talk at JSConf.eu where she presented her wish list for the future of CSS. She presents a brand-new expanded syntax which allows for prototypes, mixins, and variables and explains how a preprocessor can be used today to achieve a richer language in older browsers.

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.

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.
