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