I am trying to build a chrome extension that changes the color of websites for colorblind people. One of the features is changing the color of links that have been clicked.

I have tried "a:visited" and it works for most links, but does not work on the actual Google search page. I tried inspecting the page and found that the links are h3 elements. I then tried using the h3 selector, but it changes the color of all of them. How can I make it so that it only changes the color of the links clicked.

Here you can see that the clicked links are orange-brown and the other links are blue, but the website names remain black

Those h3 elements are inside a elements, so you can address them like this:

a:visited h3 {color: red;}

You can edit any local website (on your machine) as you like,

But can't change the server of any website including Google as it's a webserver when you refresh your page it will read from server and refreshed.
