Wildcard * in Css for Classes

Question

I have these divs that I'm styling with .tocolor, but I also need the unique identifier 1,2,3,4 etc. so I'm adding that it as another class tocolor-1.

<div class="tocolor tocolor-1">   tocolor 1   </div>
<div class="tocolor tocolor-2">   tocolor 2   </div>
<div class="tocolor tocolor-3">   tocolor 3   </div>
<div class="tocolor tocolor-4">   tocolor 4   </div>

.tocolor{
  background: red;
}

Is there a way to have just 1 class tocolor-*. I tried using a wildcard * as in this css, but it didn't work.

.tocolor-*{
  background: red;
}

Accepted Answer

What you need is called attribute selector. An example, using your html structure, is the following:

div[class^="tocolor-"], div[class*=" tocolor-"] {
    color:red 
}

In the place of div you can add any element or remove it altogether, and in the place of class you can add any attribute of the specified element.

[class^="tocolor-"] — starts with "tocolor-".
[class*=" tocolor-"] — contains the substring "tocolor-" occurring directly after a space character.

Yes you can do this.

*[id^='term-']{
    [css here]
}

This will select all ids that start with 'term-'.

As for the reason for not doing this, I see where it would be preferable to select this way; as for style, I wouldn't do it myself, but it's possible.

Answer 3

An alternative solution:

div[class|='tocolor'] will match for values of the "class" attribute that begin with "tocolor-", including "tocolor-1", "tocolor-2", etc.

Beware that this won't match

<div class="foo tocolor-">

Reference:

[att|=val]

Represents an element with the att attribute, its value either being exactly "val" or beginning with "val" immediately followed by "-" (U+002D)

Answer 4

If you don't need the unique identifier for further styling of the divs and are using HTML5 you could try and go with custom Data Attributes. Read on here or try a google search for HTML5 Custom Data Attributes
