What is the diff bw
The difference is that in case:
class="name"
: to the element will be applied only the properties of class "name" class="name-new"
: like point one, but in this case the class is "name-new" class="name new"
: in this case, to element will be applied two different classe: "name" and "new" The "space" is used to separete multiple classes, same principle is used for the "id".
Also.. the syntax class="name-new"
is not equal to use class="name_new"
.
1 and 2 - works in the same way. They are just two different classes. The corresponding style will be applied in the HTML element where they are added.
3 - The class 'name' will be applied first, then the class 'new'. The same/common style properties will be overridden by right side classes.
.name {
color:red;
}
.name-new {
color:blue;
}
.new {
font-weight: bold;
color: green;
}
<div class="name"> Name </div> // will appear in red
<div class="name-new"> New-Name </div> // will appear in blue
<div class="name new"> New Name </div> // will appear in bold-green
