Drawing Images with CSS Gradients

What I mean by "CSS images" is images that are created using only HTML elements and CSS. They look as if they were SVGs drawn in Adobe Illustrator but they were made right in the browser. Some techniques I’ve seen used are tinkering with border radii, box shadows, and sometimes clip-path. You can find a lot of great examples if you search daily css images" on CodePen. I drew some myself, including this Infinity Gauntlet, but in one element with only backgrounds and minimal use of other properties.

Let’s take a look at how you can create CSS images that way yourself.


Meet the New Dialog Element

Keith Grant discusses how HTML 5.2 has introduced a peculiar new element: <dialog>. This is an absolutely positioned and horizontally centered modal that appears on top of other content on a page. Keith looks at how to style this new element, the basic opening/closing functionality in JavaScript and, of course, the polyfills that we’ll need to get cross-browser support right.

Also, I had never heard of the ::backdrop pseudo element before. Thankfully the MDN documentation for this pseudo element digs into it a little bit more.

Signify “PDF Bombs”

Any ol' anchor link can be a link to a PDF document, but clicking a link like that thinking otherwise can be surprising and uncomfortable for a user. This CSS can visually signify those links.

/* Add " (PDF)" text after links that go to PDFs */
a[href$=".pdf"]:after { content: " (PDF)"; }

/* If file size specified as data attribute, use that too */
a[href$=".pdf"][data-size]:after { content: " (PDF, " attr(data-size) ")"; }


<p>Watch out for the <a href="some.pdf">PDF bomb</a> here!</p>

Visually becomes:

Watch out for the PDF bomb (PDF) here!


<p>Watch out for the <a href="some.pdf" data-size="2 MB">PDF bomb</a> here!</p>


Watch out for the PDF bomb (PDF, 2 MB) here!
