Bookmarklet to inject an external CSS file into any website
This bookmarklet provides an easy way to test css styles against a website without access to its server by creating a
<link/>element in the <head> of the page. It also updates it with a cache-blocking parameter if already exists.
javascript: (function () {
let cssLink = document.getElementById('injected-css');
if (cssLink === null) {
cssLink = document.createElement('link');
cssLink.id = 'injected-css';
cssLink.rel = 'stylesheet';
document.getElementsByTagName('head')[0].appendChild(cssLink);
}
cssLink.href = 'https://albertoroura.com/style.css?v=' + Date.now();
})();
