Difference beween class and id-selector.

Expand Post »

What does it matter wheater I use:

p.center
{
text-align: center;
}

And HTML:

HTML and CSS Syntax (Toggle Plain Text)
<p class="center">
Text.
</p>
<p class="center">
Text.
</p>

Or I use:

HTML and CSS Syntax (Toggle Plain Text)

#paragraphs p
{
text-align: center;
}

And then HTML:

HTML and CSS Syntax (Toggle Plain Text)
<div id="paragraphs">
<p>
Text.
</p>
</div>
<div id="paragraphs">
<p>
Text.
</p>
</div>

Could somebody explain please?

Thank You.

Re: Difference beween class and id-selector.

The difference is that an ID references a unique element on the page...i.e. there is only one element on the whole page with the ID.

A class can be used to name several different elements on the page.

In other words, you can have one div with a specific ID, but multiple divs with a specified class.

In your case, you would probably want to use a class.
