One crucial factor to consider when dealing with dual screen setups is the

Imagine you have the following code snippet :

    <ul>
        <li>Menu1
            <ul class="submenu">
                <li class="firstmenu">submenu-1</li>
                <li>submenu-2</li>
                <li>submenu-3</li>
            </ul>
        </li>
        <li>Menu2
            <ul class="submenu">
                <li class="firstmenu" id="first">submenu-1</li>
                <li>submenu-2</li>
                <li>submenu-3</li>
            </ul>
        </li>
    </ul>

In this particular case, padding-left has been applied to the first item of sub-menu's li with the following CSS:

   .submenu li:first-child{padding-left: 173px;}

However, I require a different padding for the first li of 'Menu2'. To achieve this, its ID is utilized in the following manner:

#first{padding-left:500px !important;} 

To ensure responsiveness, the following media query is employed:

    @media only screen
    and (min-width : 768px)
    and (max-width : 894px) {
        #first{padding-left:150px !important;}
    }

Nevertheless, due to the prior application of !important on the global styling, the specified responsive padding is not being considered. Consequently, a solution is sought to apply distinct padding for screen resolutions between 768 to 894.

Is there a method to accomplish this task effectively?

Answer №1

Explanation

The use of !important in CSS gives the highest priority according to the priority scheme. However, it is generally discouraged due to its impact on maintainability and specificity.

To eliminate the need for !important, alternative approaches can be employed, such as the one demonstrated below:

.submenu li.firstmenu{
    padding-left: 173px;
}

.submenu li.firstmenu#first{
    padding-left:500px
}

@media only screen
and (min-width : 768px)
and (max-width : 894px) {
    .submenu li.firstmenu#first{
       padding-left:150px;
    }
}

Additional Information

The selectors provided are similar to the original ones, but utilize the firstmenu class instead of the pseudo-selector :first-child. The distinction between .submenu li.firstmenu and .submenu li:first-child is explained in terms of selecting specific elements based on their hierarchy within the HTML structure.

By incorporating the ID of the target element (#firstmenu), precise styling adjustments can be made without relying on the !important declaration. This approach enhances code readability and flexibility compared to using overly specific styles.

Answer №2

If you're dealing with ID selectors, you can skip using !important in most cases. ID selectors have a higher priority compared to class or element selectors, unless there are many classes or elements in a single selector. Try removing !important and see if it still achieves the desired result.

.submenu li:first-child {
  padding-left: 100px;
}

#first {
  padding-left: 200px;
}
<ul>
  <li>Menu1
    <ul class="submenu">
      <li class="firstmenu">submenu-1</li>
      <li>submenu-2</li>
      <li>submenu-3</li>
    </ul>
  </li>
  <li>Menu2
    <ul class="submenu">
      <li class="firstmenu" id="first">submenu-1</li>
      <li>submenu-2</li>
      <li>submenu-3</li>
    </ul>
  </li>
</ul>

For more information, refer to the W3C spec on selectors' specificity, which includes a helpful table for comparing different selectors.
