A guide on updating pseudo-class values dynamically using CSS

Imagine a scenario where there is a navigation panel named <div class="nav"> containing 5 anchor links <a>.

CSS:
.nav a:nth-of-type(1) {
    text-decoration: underline;
}

The objective is to switch the underlined element by adjusting the CSS declaration as follows:

CSS:
.nav a:nth-of-type(2) {
    text-decoration: underline;
}

Can this be achieved? (proof of concept)

UPDATE:

I am puzzled by the negative feedback. This is simply an exploration into whether altering the content before {} brackets -> change_this { stays_the_same } could potentially be accomplished, perhaps with the aid of JavaScript.

Answer №1

Employ jquery to target 

$(".nav a").eq(2).css("text-decoration", "underline")
. You will not be altering the css directly within the file, as it is impossible. However, you can add inline css to the specific element, which takes precedence over the file's css.

Answer №2

Here is a recommended layout for you

.nav a {
  text-decoration: underline;
}
