What could be causing external stylesheet styles to take precedence over internal and inline styles?

Currently, I am working on a website that utilizes a global stylesheet which applies styles to specific element types. Personally, I find this approach inefficient. As I develop ASP.NET user controls for different pages, I consistently encounter issues where my internal and inline styles are overridden by the styles within the global stylesheet. This is happening while I am using Firefox as my browser.

For instance, I recently included a control containing a table. During development, I defined the style internally within the user control itself (not in the page head). However, the external global.css stylesheet contains the following declaration:

div#copy table {
  width: auto;
}

In contrast, my internal declaration looks like this:

table.MMPointBalance {
  border: 0 none;
  border-collapse: collapse;
  display: inline-block;
  width: 200px;
}

The width property set to 200px is being overridden by 'auto' from the external stylesheet. Although internal and inline styles should take precedence, the selector in the inline style mentioned above is also more specific compared to the global one. So, why is it not being applied?

Answer №1

Dealing with Specificity and Priority Levels in CSS can be quite challenging at times, as demonstrated in the following scenario:

The specificity of this selector is heightened by targeting a parent div with an assigned id, followed by its table child element.

div#copy table

In contrast, this only styles a table with a specific class applied to it:

table.MMPointBalance

Furthermore, if you are using !important declarations in your global.css file, you will need to address them with either the same or even more specific !important declaration.

Answer №2

The div#copy rule takes precedence due to the specificity of using an ID. To resolve conflicts, you can modify one of the rules or utilize the !important declaration.

In similar instances, I have encountered inline declarations on Telerik controls being overridden by more general global.css styles.

Inline styles defined with the style attribute will only be overwritten by external styles if the !important keyword is included.
