How Come My Class Changes Somethings But Not Others Css

CSS Programming

Have you ever experienced the frustration of trying to style elements on a web page using CSS, only to find that some elements respond to your styles while others seem to completely ignore them? I’ve been there, and I understand how perplexing and irritating it can be. Let’s dive into the reasons behind this phenomenon and explore some common pitfalls that may be causing this issue.

The Cascade and Specificity

One of the fundamental concepts in CSS is the cascade, which determines how styles are applied to elements. When multiple conflicting styles are applied to the same element, the cascade comes into play to decide which styles take precedence. This is where specificity plays a crucial role. Specificity is a weight that determines which rule applies to an element when multiple rules have competing selectors. It’s important to understand that the more specific a selector is, the higher its priority.

Inspecting the Elements

When I encounter a situation where my styles are being applied to some elements but not others, the first thing I do is to inspect the elements using the developer tools in my browser. By doing this, I can see the computed styles for each element and identify any conflicting or overridden styles. This helps me understand why certain styles may not be taking effect as expected.

Check for Conflicting Styles

One common reason for styles not being applied as intended is the presence of conflicting styles in the CSS. For example, if a general styling rule is being overridden by a more specific rule, it can lead to unexpected outcomes. It’s important to carefully review the CSS and ensure that there are no conflicting styles that might be causing certain elements to behave differently.

Understanding Inheritance

Another factor that can affect how styles are applied is inheritance. In CSS, certain properties are inherited from parent elements to their children. If a particular style is not being applied to an element, it’s worth checking if the style is being inherited from a parent element and overridden by a more specific rule somewhere else in the stylesheet.

External Libraries and Frameworks

When working with external libraries or frameworks, such as Bootstrap or Materialize, it’s essential to understand how these tools may impact the styling of your elements. These libraries often come with their own set of predefined styles and classes, which can sometimes conflict with custom styles you’re trying to apply. It’s crucial to carefully manage the interaction between your custom styles and those provided by external libraries to ensure consistency across all elements.


As I’ve delved into the intricacies of CSS styling, I’ve come to appreciate the complexity involved in ensuring consistent and predictable styling across different elements. By understanding the principles of the cascade, specificity, inheritance, and the impact of external libraries, I’ve been able to overcome many challenges in getting my styles to behave as intended. Next time you find yourself scratching your head over why some elements respond to your styles while others don’t, consider these factors and you may well uncover the root of the issue.
