Selectors 5.1 Pattern matching In CSS, pattern matching rules determine which style rules apply to elements in the document tree. These patterns, called selectors, may range from simple element names to rich contextual patterns. If all conditions in the pattern are true for a certain element, the selector matches the element. The case-sensitivity of document language element names in selectors depends on the document language. The following table summarizes CSS 2.1 selector syntax: 5.2 Selector syntax simple selector is either a type selector or universal selector followed immediately by zero or more attribute selectors, ID selectors, or pseudo-classes, in any order. Note: the terminology used here in CSS 2.1 is different from what is used in CSS3. selector is a chain of one or more simple selectors separated by combinators. Combinators are: white space, ">", and "+". The elements of the document tree that match a selector are called subjects of the selector. 5.2.1 Grouping Example(s): is equivalent to: [att]
Score Quick Style Wins with These CSS Animation Tools for WordPress Animation can help. But not just any old random animated flashy thing. Those are annoying. CSS animations allow transitions from one CSS style to another. Why CSS instead of JavaScript? Why use CSS when you can use JavaScript or several other scripts for creating animations? Here are a few good reasons: They’re easy. Basically, animating with CSS is the simplest way to move something on the screen and add some animated flare to your site. How to Create CSS Animations by Hand There are several ways to create CSS animations. Note: Key frames is an old term from back in the day of hand-drawn animation. The Animation Just like old cartoons, the animation is defined with keyframes. The CSS keyframe is a list of values that describe the animation. Let’s look at a few examples. Transitions Transitions let you move an object from point A to point B without any points in between. Here’s some example code from Google Developers: CSS animations are usually vendor prefixed.

The Debate Around "Do We Even Need CSS Anymore?" | CSS-Tricks This has become quite the hot topic lately. It's been talked about at a number of conferences and meetups I've been at personally lately. I've seen slide decks on it. I thought we could have a little campfire here and talk about it as rationally as we can, covering all the relevant points. We obviously still need to style things Nobody is saying we don't need styles. The worst things about CSS are the "Cascading" and the "Sheets" What does anyone have against CSS? These are the main arguments against CSS: Everything is global. What is the alternative to CSS then? The alternative is inline styles. We're talking: I haven't heard anyone yet argue you should apply these styles directly to HTML you author. React is driving a lot of these thoughts React is a JavaScript library that helps with view concerns in websites. One of it's core concepts is the "Virtual DOM". This coupling is real, and it is unavoidable. React has the ability to manage inline styles built right in. Cascade-less All JavaScript

The Back(side) of the Class, by Stephen Hay Have you ever been taught that “modularizing” CSS via an endless number of “reusable” object-like “classes” is the “proper” way to use CSS on “large-scale websites”, or have you taught others that these are “best practices”? If you answered yes to the above questions, then you, my friend, are going to absolutely hate this session.

A Look at Some CSS Methodologies By Kieran Potts CSS is notoriously difficult to manage in large, complex, rapidly-iterated systems. One reason is CSS lacks a built-in scoping mechanism. Everything in CSS is global. Extended CSS languages, a.k.a. Until CSS gets its own native scoping mechanism, we need to devise our own system for locking down styles to specific sections of an HTML document. CSS methodologies are the solution. In this article, we will take a look at these CSS methodologies: Object-Oriented CSS (OOCSS)Block, Element, Modifier (BEM)Scalable and Modular Architecture for CSS (SMACSS)SUIT CSSSystematic CSS Full disclosure: I’m the creator of Systematic CSS. CSS methodologies are formal, documented systems for authoring CSS in a way that allows us to develop, maintain and scale the front-end as a set of small, isolated modules. Adopting a CSS methodology — even if it’s one that you create yourself — will make it easier for you to design and iterate on your web design projects, regardless of scale and complexity. <!
Tips for Writing Modular CSS Matt Lambert No matter how much you love CSS, no one enjoys writing or maintaining style sheets that are 2000+ lines of awesomeness. The smart way to approach your CSS is from a modular stand point. Properly organizing your CSS, breaking it into smaller chunks, and naming classes in a generic way are a few places to start. Let’s review some of my top tips for writing modular CSS Use SMACCS There’s a few systems out there for organizing your CSS but the best one I’ve found is SMACCS (Scalable and Modular Architecture for CSS). Base All native HTML selectors, element selectors, descendant/child selectors, and pseudo-classes. Layout Styles specific to the layout of your website or template. Module Reusable classes or components. States Here you add any state change CSS like alerts or form validation styles. Theme This section is optional but if you have any theme specific CSS that doesn’t fit into any of the above sections, it should go here. Less Variables Less Components One Theme to Rule Them All
CSS Sprites: What They Are, Why They're Cool, and How To Use Them By Chris Coyier On This article has been revised and re-written several times since its very first publication in 2007, to keep the information current. The most recent revision was done by Flip Stewart in January 2015. #What are CSS Sprites? Spoiler alert: they aren't fairies that write your stylesheets for you. To summarize: the term "sprites" comes from a technique in computer graphics, most often used in video games. CSS Sprites is pretty much the exact same theory: get the image once, and shift it around and only display parts of it. #Why use CSS Sprites? It may seem counterintuitive to cram smaller images into a larger image. Let's look at some numbers on an actual example: That adds up to a total of 14.38KB to load the three images. While the total image size (sometimes) goes up with sprites, several images are loaded with a single HTTP request. Thus, sprites are important for the same reasons that minifying and concatinating CSS and JavaScript are important. $ npm install sprity -g

CSS-Only Responsive Layout with Smooth Transitions A tutorial on how to create a 100% width and height smooth scrolling layout with CSS only. Using a radio button navigation and sibling combinators we will trigger transitions to the respective content panels, creating a "smooth scrolling" effect. View demo Download source In this tutorial we will create a responsive 100% width/height layout with some smooth page transitions. The idea is to have some content panels and a navigation which will allow us to navigate between the panels. Please note: the result of this tutorial will only work as intended in browsers that support the respective CSS properties. Note that we will exclude vendor prefixes in this tutorial. The Markup The structure will be consist of a main container with the class st-container which will contain the radio buttons and link, and the wrapper with the class st-scroll for the panels. What we want to do is basically move the panel wrapper by changing it’s top value and bringing the respective panel into the viewport.
How to make a carousel using only HTML and CSS (no JavaScript required!) Recently, I’ve been working on a site that uses a CMS that’s a bit limiting. I can add my own HTML and CSS to the site, but JavaScript is off-limits. The designs I’m working from included a carousel. I had some ideas of how I could make that work using CSS animations and the transform property, but that would leave me with a carousel that scrolled automatically and didn’t allow for user input which wasn’t really what I was looking for. This is the first item Idque Caesaris facere voluntate liceret: sese habere. This is the second item Vivamus sagittis lacus vel augue laoreet rutrum faucibus. And finally, the third Quis aute iure reprehenderit in voluptate velit esse. Let’s build one! The structure The structure of our carousel goes something like this: We have a main div.carousel-wrapper that gives our carousel its size. Each of our div.carousel-item elements have some content within them, and two links, a.arrow-prev and a.arrow-next, which we use to cycle between the carousel items. <!
Stop Printing Ugly WordPress Pages With This Easy Fix As a WordPress designer, you fret and worry about how your pages and your posts look – on the screen. That’s what it’s all about, right? You look at that new travel-story website you just finished, and it looks great in all the current web browsers. It’s fabulous. A week later, you’re sitting at your computer when the client calls and says, “Hey, our customers are trying to print stuff off that new website you made for us, and everything is a mess – you have to fix that – now!!!” Then you (for the first time ever) choose your browser’s print command, your printer starts whirring and clacking, and by the time you slide over to your printer it’s already printed out three sheets of paper when it should have just been one sheet. Your client is right (aren’t they always?). Your head spins as you try to figure out what’s wrong and what to do, as the enraged client continues yelling into the phone – her voice getting higher and louder. Do People Actually Print Web Pages? Don’t worry.
