What is the DOM?

A reader recently wrote in asking me what the DOM was. They said they've heard it mentioned and alluded to, but aren't sure they really understand it.

We can fix that. …

On interviewing front-end engineers

Nicholas C. Zakas with a follow up to Philip Walton's article.

Front-end engineers are, of course, specialists. We care about things that seem insane to others: understanding differences between dozens of browsers, pixels vs. ems, PNG vs. JPEG, compatibility …

LICEcap

Animated GIFs, aside from being megalolfunny, can be tremendously useful in communicating an idea. Like this or this. I get asked often how I make those. There is nothing to it, just use this app.…

Make Sure Your Columns Don’t Collapse Horizontally

You might be familiar with elements collapsing vertically. If an element only contains other elements that are floated, the parent element will collapse to zero height. We often employ the clear fix for that. But if an element doesn't contain …

CSS is 17

Some nice history on the birth of CSS by John Allsopp.…

The Growth of CSS Repos on GitHub

Interesting statistic uncovered by Donnie Berkholz: the number of repos that GitHub classifies as "CSS" (has more CSS in it than any other language) grew 13.6x in 2013. Doubling would be crazy, this is something else entirely. Assuming this isn't …

Myth

I thought I'd weigh in here...

  1. Calling it a "postprocessor" is weird. It gets parsed into CSS before the browser sees it, so it's a preprocessor. If something parses the CSS out from the browser, it can be a postprocessor,

About Variables in CSS and Abstractions in Web Languages

Variables are coming to CSS. They already have implementations, so there is no stopping it now. Firefox has them in version 29 and Chrome has them unprefixed in 29+ if you have the "Enable experimental Web Platform features" flag turned …

Line Menu Icon… That Is A Menu

I had a dumb little idea the other night so I just coded it up (as you do). You know those little icons that have come represent navigation? We've called them Three Line Menu icons around here, but otherwise known …

What You May Not Know About Z-Index

It controls which element is "on top" visually when they happen to overlap, right? Right. But there is more to the stacking order, much of which you can't control. You can control stacking contexts though, which kind of reset the …

New Poll: Command Line Usage

I have a feeling the readers of CSS-Tricks represent a fairly wide range of job types and skill levels. It would be interesting to know how frequently used command line usage is amongst the general web worker population.…

Animated SVGs

Mike Fortress explains animation with <svg> with a specific example involving charts on Sprout.

It's funny how SVG has all these great features like gradients and filters and animations that we have in CSS, but the syntax is so different. …

Chrome DevTools for Mobile

Emulate mobile devices directly through DevTools, simulating touch events, mimicking screen size, and spoofing user agent.

Plug in a mobile device over USB and use Chrome DevTools on the actual mobile browser. Push your local site to the mobile device …

SVG Tabs (Using an SVG Shape as Template)

An excellent feature of SVG is that you can define a shape (or set of shapes) once, and then use it multiple times throughout a page. You can even apply different fills and filters and whatnot to the different versions. …

A Blue Box

A little meme went around CodePen the other night. A Blue Box. I'm not sure how it started, but lots of people started posting code of different ways to draw a blue box. It's weird, it's funny, but it's also …

Turn Off Hovers on Scroll

Sometimes hover effects can cause redraws and repaints and whatnot that take time and reduce performance. As you scroll down a page, you're likely inadvertently triggering hover events that have no meaning while you scroll. Turning them off (via CSS's …

Dom Monster

A bookmarklet you can click to give you performance information specifically related to the DOM. E.g. duplicate IDs, excessive stylesheets, excessive nesting, empty nodes, HTML comments, etc.…

Responsive Comments

Meaning like <!-- these kind of comments -->. You put a media query in a data-* attribute of a parent element and it will determine if that block of commented HTML should be un-commented or not. A form of …

What Screens Want

I'm happy to be the last person in our industry to link to Frank Chimero's beautiful essay on screen design (watch the colors slowly fade emphasizing the "flux" point). A small point I like:

We need abstractions, otherwise we’d be …

Introducing Scut, a new Sass utility library

The following is a guest post by David Clark. I think David's new Sass library "Scut" is pretty interesting. It's like a design utility library, which is distinct from a design pattern library in that it enforces no particular

Why Responsive Images Is So Hard

Perhaps you've been keeping up on the responsive images #hotdrama? If you have no idea what "responsive images" means, it means serving different images under different circumstances. How to do that and what those circumstances are vary widely.…

Namespaced Events in jQuery

It's really easy to add an event listener in jQuery. It's equally easy to remove an event listener. You might want to remove a listener because you don't care to perform any actions on that event anymore, to reduce memory …

CSS Stats

Some heuristics on CSS that you can run on any site. Started with the sharing of that data from several popular sites. It's open source and I would think the most valuable feedback to give would be "what data

The CSS Standards Process

Grade components, not browsers

It's live!

If this is the first you've heard of it, it's a contest where you get a Photoshop document and have two weeks to convert it into HTML and CSS. You're judged on an established set of criteria. …

HTML Imports

Essentially a way to import a block of dependancies (scripts and styles) into an HTML document.

<link rel="import" href="imports.html">

It doesn't actually just plop the content from the referenced file where you call it though, like an @import does in …

-moz-gone

Mozilla says they "will no longer ship new 'moz'-prefixed APIs" as part of an overall philosophy of: "Is this good for the Web?"

Blink has also said this. Word has it WebKit still plans to use them as they …

Transformer Tabs

Tabs are a simple design pattern in which a row of links are obviously clickable navigation and when a link is clicked, new content is shown. There are loads of variations of course, but it's one of the most ubiquitous …

Which CSS Measurements To Use When

I agree with these general guidelines from Dudley Storey. Funny how these general-purpose length measurements have fallen into to some pretty specific niches.…

Email Domain Datalist Helper
