Incorporating existing CSS styles into a new CSS file

Question

Incorporating existing CSS styles into a new CSS file

I'm a little confused by the title, so let me clarify with an example. Let's say I have the following CSS code inside a file:

#container_1 {
    width:50%;
    border:1px solid black;
}

#container_2 {
    background-color:red;
    padding:5px;
}

If I want container_2 to have the same styles as container_1 (50% width and 1px border), is there a way to do this without repeating the CSS properties in container_2's rules?

Could it be something like this:

#container_2 {
    include:#container_1;
    background-color:red;
    padding:5px;
}

Thank you!

Answer №1

In the realm of CSS, it is not straightforward to directly inherit properties from one class to another; however, with a simple workaround, we can streamline this process by writing code like the following:

#container_1,#container_2 {
    width:50%;
    border:1px solid black;
}

#container_2 {
    background-color:red;
    padding:5px;
}

By adopting this approach, #container_2 will possess all the characteristics of #container_1 except for its unique attributes.

Alternatively,

We have the option to utilize Sass to accomplish the same goal. Sass introduces a feature known as @mixin, which allows us to merge styles effectively.

For example:

@mixin reset-list {
  margin: 0;
  padding: 0;
  list-style: none;
}

@mixin horizontal-list {
  @include reset-list;

  li {
    display: inline-block;
    margin: {
      left: -2px;
      right: 2em;
    }
  }
}

Include a comma in the CSS code to ensure that container_2 matches the style of container_1

#container_1, #container_2 {
    width: 50%;
    border: 1px solid black;
}

#container_2 {
    background-color: red;
    padding: 5px;
}

Here is an alternative way to structure the code:

#box_1, 
#box_2 {
    /* Common Styles */
    width:50%;
    border:1px solid black;
}

#box_2 {
    background-color:red;
    padding:5px;
}

Alternatively, you could create a single class for all boxes in HTML.

#box_main {
    /* Common Styles */
}
#box_2 {
    background-color:red;
    padding:5px;
}    

<div class="box_main box_2"></div>
