Question

I read an article where it was recommended that we should ONLY use classes in our markup and only use ids when we need to refere to it from javascript (as it is easier to attach functions to ids)

At the moment I only use classes when I have more than one element that needs the similar style. However the article (which I THINK I read – but have no reference) stated that we should use classes throughout

I would do this:

<header id="banner"></header>

Where as the recommendation was :

<header class="banner"></header>

(even though the banner is only used once per page)

is this the new “good practice”?

Thanks

As far as I know you are correct, you should use classes when you need to style multiple elements and IDs when you are only styling a unique element.
