Class Selector Rules

HTML-CSS

Hi guys :slight_smile:

May you kindly please explain when you are allowed to use a period before a “class” selector and when are you not because I have had instances where it would give me an error message if there’s no period (,) at the beginning of the “class” selector.

For instance: address / .address

I really appreciate the help & support you guys.

if there’s no period (.), I meant…

Putting a period before something means you are targeting a class with that name. So .address would mean you are targeting all elements that have a class of address.

Without the period you are targeting the element itself. So address would mean you are targeting any address element on the page.

This makes total sense.

Please check the below attached solution.

.img {display: block;
      margin-left: center;
      margin-right: center;
}

This resulted in an error as it was targeted at a particular image. So, now I get it.

Thanks a lot :slight_smile:

<img> is not a class. It is an element and so you do not use
class selectors for classes example class="abc" that are within an element.
Thus you do not use the dot notation for class selectors
