Is it possible to implement a unique style exclusively for my application's components?

Recently, I've been trying to apply a universal style rule to my entire app similar to this:

  div {
    width: 100%;
  }

At first, everything seemed to be working perfectly. However, when I began integrating third-party components that have their own default style expectations for div, issues started to arise. This meant I had to constantly fix conflicts whenever they occurred.

I'm wondering if there's a way to implement a workaround so that the components in my application maintain a default style without interfering with the styles of third-party elements. Currently, I use styled-components for styling, but I am open to solutions using other libraries as well.

Answer №1

To easily identify third party components, consider adding a class like thirdParty. If that's not possible, try wrapping the third party components with a tag. Then you can make use of :not() in your CSS to style them differently:

/* Your local styles */
div:not(.thirdParty, .thirdParty *) {
  width: 100%;
  background-color: lightgreen;
  text-align: center;
}
<div>Local component one</div>

<div class="thirdParty">Third Party Parent
  <div>--- Third Party Child
    <div>------ Third Party Grandchild </div>
  </div>
</div>

<div>Local component two</div>
