A Brackets extension that allows you to easily insert a variety of HTML elements into your document.. leverage Jetpack for extra functionality and Local It’s no longer necessary in Chrome (bug fixed) but people will be confused. The spinner and the blank screen became one and the same. Or you could do something like calc(100% - var(--card-padding) * 2) to “fake” block level elements. Adding a media query to adjust parts of the skeleton at different breakpoints is now also quite simple: Browser support for custom properties is good, but not at 100%. a decision I'm very happy with. Prev. Performance is not only a developer’s responsibility, building an experience that works with slow connections can be a design challenge as well. Seems like a good opportunity to provide promotional info or a call to action for the user. Perceived performance is a measure of how fast something feels to the user. The idea is that users are more patient and will think of a system as faster if they know what’s going on and can anticipate content before it’s actually there. If we want to change that, we’ll have to define explicit dimensions for them. Simple. Thats the whole point of perceived performance. Meh. Basically, you want the radial gradient to have crisp edges, as opposed to the default blending it does.

While I like the concept of skeleton elements, I’ve always felt like if you need animation in one, your “perceived” performance is still terrible since users are still waiting a noticeable amount of time for actual content. CodePen is a place to experiment, debug, and show off your HTML, CSS, and The tricks we use to create a perception of something loading become stale and the trick itself becomes as annoying as the original wait time. Thank you for the article and follow up codepen! Nobody is actually “tricked” into thinking that this is not a loading state – it is just a type of spinner that conveys a little more information.

Plus it’s not responsive, and if we ever decided to adjust some of the content card’s styling, we would have to duplicate the changes to the skeleton image so they’d match again. For a web app, this concept might include displaying “mockups” of text, images or other content elements – called skeleton screens . Easily insert a variety of HTML elements into your document.
