utilizing a specific pseudoclass

To customize the bullets of unordered list items, I am utilizing a pseudo-class to display 4 boxes and a white right pointing arrow (▢▢▢▢▷) by default:

      li:before {
        content: "\25A2\25A2\25A2\25A2\25B7";
        padding-right: 0;
      }

In addition, I want to introduce another pseudo-class that will alter specific list items to show 4 boxes with a black right pointing arrow (▢▢▢▢▶):

      .known li:before {
        content: "\25A2\25A2\25A2\25A2\25B6";
        padding-right: 0;
      }
<li>general data</li>               <-the default for most items
<li class="known">marked data</li>  <-a few select cases

Unfortunately, it seems that using a class selector along with pseudo-classes is not effective in achieving this objective.

My knowledge of pseudo-classes is still limited as I have recently discovered how to change all bullet points but struggle with applying them conditionally based on classes.

At the moment, I would be required to manually modify each li element to include the desired box and arrow styles since the current method does not support conditional application using classes.

Answer №1

To select the element, you need to use li.known::before:

li::before {
     content: "\25A2\25A2\25A2\25A2\25B7";
     padding-right: 0;
}
 
li.known::before {
    content: "\25A2\25A2\25A2\25A2\25B6";
    padding-right: 0;
}
<li>general data</li>
<li class="known">marked data</li>

In the code, .known li::before is used to target li elements that are children of an element with the class name "known". The space between selectors indicates a descendant relationship (not direct).

Answer №2

To target list items with the specific .known class, you can utilize the code provided below:

li.known:before {
  content: "\25A2\25A2\25A2\25A2\25B6";
  padding-right: 0;
}

If you use .know li:before, it will apply to all <li> elements within any .known elements.

However, by using the aforementioned method, you will be targeting only those <li> elements that have the .known class specifically.
