I searched the web thoroughly over and over again, but I coudln't find the answer I was looking for. The question is : Why use ID when you can do the same task with class ? I mean, ok I know that ID's are just for one time use and classes are for many, but what forbids me from using the class selector for just once ? So, according to this, what is the purpose of

Change color of an anchor when clicked

由 廉价感情. 提交于 2021-02-05 04:46:59
问题 i want that when i click this link its color changes to the given color <li id="press"><a href="<?=base_url()?>index.php/page/press">Press</a></li> 回答1: The CSS declaration :active will accomplish what you're after. http://www.w3schools.com/CSS/pr_pseudo_active.asp Example. a:active { color: #C00; } NB. a:active MUST come after a:hover in the CSS definition in order to be effective! 回答2: All links? a:focus { color: orange; } Some links? Give them a class, eg <a class="foo" ...> : a.foo:focus
