What could be the reason for not just removing the pseudo-class, but instead deleting the entire CSS document altogether?

var style = document.styleSheets[1]  

style.deleteRule(`.block__header::after`)

console.log(`.block__header::after`)

What is preventing it from being removed from the CSS document?

The pseudo-class is still found in the console, and when trying to delete it by looping through all stylesheets, it removes all CSS from the document.

for (var i = 0; i < 1000; i++) {
     style.deleteRule(`.block__header::after`)
}

Answer №1

To remove a CSS rule, the method deleteRule requires an index as a parameter. For more information, refer to the documentation on deleteRule. You can also check out this example on how to achieve this using JavaScript: Remove CSS rules by JavaScript
