Could someone help me differentiate between the [att|=val]
and [att~=val]
attributes in CSS? I'm having trouble grasping the concept.
Thank you!

[attr|=val]
is used to select elements with an attribute value that matches a word in val
, regardless of its form. For example, [class=div]
would match .my-div
and .div
, but not .mydiv
.
[attr~=val]
is used to select elements with an attribute value that exactly matches the complete word in val
. So, [class~=div]
would only match .div
, excluding .mydiv
or .my-div
.
Here's an example:
HTML
<div id="myDiv"></div>
<div id="myDiv2"></div>
<div id="new-div"></div>
CSS
div[id|=myDiv] {
/* Selects the first div */
}
div[id|=my]{
/* Selects the first two divs */
}
div[id|=new]{
/* Selects the second div - the hyphen acts as a word separator */
}
div[id~=Div]{
/* Does not select anything - "Div" is not considered a separate word */
}
