Hi,

I have a basic CSS question. I would like to know the difference between these two blocks of classes. What's the difference between
fieldset.login label and fieldset label.login in the example below ?

CSS

fieldset.login label
{
    display: block;
}

fieldset label.login
{
    display: inline;
}

Solution 1

The first is generic, the second specific. For the first a fieldset class called login is applied to all labels within the fieldset whereas in the second only labels with a class of login within the fieldset will have the class applied. Fairly sure that's it.

The difference is:

this assigns display:block; to all labels contained within fieldsets with class "login"

fieldset.login label
{
    display: block;
}

whereas this assigns display:inline; to all labels with class "login" contained within all fieldsets

fieldset label.login
{
    display: inline;
}

Hi

The above explanations are correct. Try this visual example as well to understand clear.

the CSS..

C#

fieldset.login label
{
    color:Blue;
}
fieldset label.login
{
    color:Green;
}

the HTML...

XML

<fieldset>
   <label class="login">It is login class on the label</label>
 </fieldset>
     <fieldset class="login">
            <label >It is login class in the FieldSet</label>
 </fieldset>

This example is self explainable
