``Modeling CSS Classes Using the Adjacent Sibling

As a coding novice, I challenged myself to rebuild my WordPress site using HTML, CSS, and JavaScript. In my quest for the best way to create a responsive navigation bar, I stumbled upon an example on W3Schools.

My dilemma lies in how to handle Adjacent Classes, as my CSSLint flags it as bad practice. Should I stick with them and sacrifice compatibility with IE 6, or should I learn the better standard?

@media screen and (max-width: 600px) {
  .cMainNav.responsive {
    position: relative;
  }

  .cMainNav.responsive a.icon {
    position: absolute;
    right: 0;
    top: 0;
  }

  .cMainNav.responsive a {
    float: none;
    display: block;
    text-align: left;
  }
}

Answer №1

It appears there might be a misunderstanding. Adjoined classes are not considered standard practice in CSS. This concept is simply one aspect of css specificity.

For example, if you have an element with two classes:

<div class="square red"></div>
<div class="square green"></div>

You can target their combination like this:

.square.red {}

CSSLint may caution against using overly long and complex selectors like the following example:

.square.red.fixed.flex.button{}

If precise targeting is needed, it's advisable to use an id or a specific class instead.

<div id="loginModal"></div>

In essence, these tools are available for your use. Learn more about specificity and remember that there isn't necessarily a "wrong" choice, but misuse of any option can occur.
