"Modify the CSS color of h1 based on the presence of a specific class containing spaces in a div

I am currently attempting to modify the color of a heading by referencing a specific div's class.

My attempts so far include:

.pagetitle-title.heading {
  color: purple;
}
<div class="container">
  <h1 class="pagetitle-title heading">IT•ONE Method</h1>
</div>

I have even tried:

h1 {
  color: purple; 
}

Answer №1

As previously mentioned in my comment, it appears to be a typical situation of "CSS overwrite". One technique to prevent this is by utilizing the CSS property !important to specify to the browser which CSS rule should take precedence and not be overridden.

For instance: color: purple !important;

CSS implements styles based on the order they are loaded. If you have one CSS file with x rules and a second CSS file with y rules targeting the same elements, the last loaded CSS file will usually overwrite the styles of the preceding one.

This sequence is referred to as the top-down rule, and can only be superseded by the !important property and in-line CSS. The !Importantproperty typically overrides any in-line CSS.

Understanding the concept of the top-down rule, if you have the ability to modify the CSS and/or control the loading order of CSS files, you can ensure that your own CSS rules are applied by arranging for them to be loaded as the final included file in your project.

For example:

<head>
<link rel="stylesheet" type="text/css" href="loadedfirst.css">
<link rel="stylesheet" type="text/css" href="loadedsecond.css">'
<link rel="stylesheet" type="text/css" href="loadedlast.css">
</head>

If these 3 files contain rules affecting the same elements, the loadedlast.css file is the CSS that will prevail over the previous ones, except when using the !important property and in-line CSS. By managing the sequence of your CSS files, you can avoid the need for employing techniques like relying on the !important property.

Answer №2

  1. Make sure to double-check your "stylesheet" link for your CSS file
  2. Access your debug console and locate the h2 element to confirm if the CSS options are being applied correctly
  3. Experiment with a different hex color code to see if it resolves the issue
  4. Add the "!important" declaration after your color code

    color: purple!important;

I have reviewed your code and it appears to be the correct approach for adjusting this color, so I recommend following my checklist first before providing us with your feedback.

Answer №3

To minimize the use of important, I prefer to target a more specific parent element and avoid adding it unnecessarily. For instance, I aim for higher up in the parent hierarchy and try to pinpoint the div with precision. In case the desired styling is not achieved, only then do I resort to using important.

.wrapper h2.subtitle-text.highlight {
    background-color: teal;
}

Resorting to the important rule should be seen as a last resort after exhausting other options.
