ct.css — Efficiency Hints by way of Injected Stylesheet Alone

No Comments

That is some bonafide CSS trickery from Harry that offers you some generic efficiency recommendation primarily based on what it sees in your <head> component.

First, it’s attainable to make a <fashion> block seen like some other component by altering the show away from the default of none. It’s a pleasant little trick. You possibly can even try this for issues within the <head>, for instance…

head fashion,
head script {
show: block;

From there, Harry will get very intelligent with selectors, figuring out problematic conditions from the utilization and placement of sure tags. For instance, say there’s a <script> that comes after some kinds…

<hyperlink rel=”stylesheet” href=”…”>
<script src=”…”></script>
<title>Web page Title</title>
<!– … –>

Properly, that’s unhealthy, as a result of the script is blocked by CSS seemingly unnecessarily. Maybe some refined efficiency tooling software program might inform you that. However you understand what else can? A CSS selector!

head [rel=”stylesheet”]:not([media=”print”]):not(.ct) ~ script,
head fashion:not(:empty) ~ script {


That’s kinda like saying head hyperlink ~ script, however slightly fancier in that it solely selects precise stylesheets or fashion blocks which can be actually blocking (and never itself). Harry then applies styling and pseudo-content to the blocks so you should utilize the stylesheet as a visible efficiency debugging software.

That’s simply darn intelligent, that. The stylesheet has a great deal of little issues you’ll be able to take a look at for, like attributes you don’t want, blocking sources, and parts which can be out of order.
