Certain CSS classes are functioning properly, while others are not operating as expected

I am in the process of developing an ASP.Net page and utilizing Bootstrap, which has been functioning properly. Additionally, I have integrated a custom stylesheet to refine the appearance of the page. However, within the last couple of days, any new classes created in the custom stylesheet fail to apply changes to elements on the page. For instance, I have a basic div element on the page that I am attempting to change the background color for. Despite creating a CSS class ".background-pink" that successfully turns the div pink, a subsequent class ".background-blue" in the stylesheet fails to apply the style when assigned to the div. This issue persists across all newly created classes in the stylesheet.

I have attempted various troubleshooting steps such as clearing browser caches, using incognito modes, and testing on different browsers with no success. Syntax errors in the CSS have been ruled out, as the class names are recognized by the intelliprompt in Visual Studio. Renaming the stylesheet and rebuilding the application also did not resolve the issue. Interestingly, applying the styles inline to the div works without any problems.

This problem is quite perplexing to me, and any suggestions or insights would be greatly appreciated. Thank you!

.background-pink {
  background-color: #E33491;
}

.background-blue {
  background-color: blue;
}

.font-white {
  color: white;
}
<div class="background-blue">test</div>
<div class="background-pink">test</div>
<div style="background-color:blue">test</div>

Below is the complete stylesheet:

.negativetopmargin {
    margin-top: -5px;
}

.background-pink {
    background-color: #E33491;
}

.background-blue {
    background-color: #E33491;
}

.font-white {
    color: white;
}

.center-div {
    position: relative;
    margin-left: auto;
    margin-right: auto;
}

body {
    font-family: 'Palanquin', sans-serif;
    background-color: red;
}

.padding-4 {
    padding: 4px;
}

It is worth noting that the font settings throughout the page are correct according to the body method, but changes to the background color have not been successful.

Answer №1

Consider implementing the following rule within your custom class .background-blue using the !important declaration:

.background-blue
{
  background-color: blue !important; 
}

It appears that another class in your stylesheet is overriding the styling of the .background-blue class.

Assuming that the issue is specific to the .background-blue class, the use of the !important rule assigns priority to this class for a blue background.

On a side note, refer to this article before including the !important rule. It's advisable not to overuse it.


Additional Example

.background-pink {
  background-color: #E33491;
}

.background-blue {
  background-color: blue !important;
}
<div class="background-blue ">test</div>
<div class="background-pink">test</div>
<div style="background-color:blue">test</div>

<!-- The following div applies both background-blue and background-pink classes. 
Since background-blue has the !important rule, it overrides the preceding class, background-pink. -->
<div class="background-blue background-pink">test</div>


It is possible that the server recognizes your updated stylesheet but sends headers instructing the browser to use a cached version. Use developer tools with F12 to inspect the headers during page load.

A hard refresh with ctrl + F5 typically resolves the issue, but in complex situations, manual header adjustments may be necessary. Refer to this answer for more details.
