What causes a CSS class to have priority over another?

I've encountered a challenge in my Vue.js project where I'm utilizing Vuetify and vue-flash-message. My goal is to change the warning message background to 'blueviolet' by adjusting its style:

.flash__message.warning {
  color: #ffffff;
  background-color: blueviolet;
  border-color: #ef9e3b;
}

However, the '.warning' class in Vuetify seems to be overriding my changes, as shown in the screenshot https://i.sstatic.net/eEgWk.png.

I'm curious if anyone can shed light on the technique being used here. Additionally, I would appreciate guidance on the correct approach to achieve the desired 'blueviolet' message background in this scenario.

Answer №1

The problem lies with the second class in your code, which is forcing the browser to display a yellow background using the !important tag. The !important tag overrides any other styles that may conflict with the class. In order to resolve this issue, you can take two approaches:

A) Remove the !important declaration from the yellow styles and apply it to the purple styles instead.

B) Completely eliminate the yellow styles from your code.

While Option A may seem like the more logical choice, it ultimately depends on the specific environment you are working in and your code etiquette preferences for the project. Personally, I recommend simplifying your code by avoiding the use of excessive !importants in web projects.

For more detailed information on the !important utility, you can refer to this informative blog post: !Important Utility information

I hope this explanation helps you resolve the issue at hand.
