How to Overcome Unwanted HTML Button Background Colour in WordPress
As a WordPress developer, you may have encountered a frustrating issue where the background colour of your HTML buttons doesn't match your desired design. This problem is often caused by CSS specificity, a concept that determines which styles take precedence when multiple rules apply to the same element.
In this blog post, we'll dive into the root cause of this problem and explore a reliable solution to ensure your buttons display the correct background colour on your WordPress website.
Understanding CSS Specificity
CSS specificity is a set of rules that determines the priority of styles applied to an HTML element. When multiple CSS rules target the same element, the browser uses the specificity of each rule to decide which one should take precedence.
The specificity of a CSS selector is calculated based on the following factors, in order of importance:
- Inline styles: Styles applied directly to an HTML element using the
style
attribute have the highest specificity.
- IDs: CSS rules that target an element using an ID selector (e.g.,
#myButton
) have a higher specificity than other selectors.
- Classes, attributes, and pseudo-classes: CSS rules that target an element using a class selector (e.g.,
.myButton
), attribute selector (e.g., [type="submit"]
), or pseudo-class (e.g., :hover
) have a higher specificity than element (tag) selectors.
- Element (tag) selectors: CSS rules that target an element using a tag name (e.g.,
button
) have the lowest specificity.
The more specific a CSS selector is, the higher its specificity, and the more likely it is to be applied to the target element.
The Problem: Unwanted HTML Button Background Colour
Let's say you have an article element in your WordPress content, and you've applied a specific style to the buttons within that article:
.myArticle button {
background-color: #232323;
color: black;
}
Now, if you have a button in your article that doesn't have its own class or ID, it will inherit the styles from the parent .myArticle button
selector. This means the button will have a dark grey background colour, which may not be the desired look you're going for.
The reason for this is that the .myArticle button
selector has a higher specificity than the default button styles applied by the browser. The browser will apply the more specific styles, resulting in the unwanted button background colour.
The Solution: Properly Style Your Buttons
To overcome this issue, you need to make your button styles more specific than the parent element's styles. Here's how you can do it:
-
Assign a unique ID or class to your button:
<button id="myButton">Click me</button>
-
Create a CSS rule that targets the button's ID or class:
#myButton {
background-color: "your-desired-color";
color: "your-desired-color";
}
By using an ID selector (#myButton
), you're ensuring that your button styles have a higher specificity than the parent element's styles (.myArticle button
), overriding the unwanted background colour.
Alternatively, you can use an attribute selector to target the button element based on its type
attribute:
.myArticle input[type="submit"] {
background-color: "your-desired-color";
color: "your-desired-color";
}
This approach is useful if you have multiple buttons within the .myArticle
element and you want to style them all consistently.
Real-World Example
Let's consider a real-world example to solidify our understanding.
Imagine you have a WordPress website with a blog section. Within the blog posts, you have a call-to-action (CTA) button that you want to style differently from the other buttons on the page.
Here's the HTML structure:
<div class="blog-post">
<h2>Blog Post Title</h2>
<p>Blog post content goes here.</p>
<a href="#" class="cta-button">Sign Up Now</a>
</div>
And the CSS:
/* General button styles */
button, .cta-button {
background-color: #007bff;
color: #fff;
padding: 10px 20px;
border: none;
border-radius: 4px;
cursor: pointer;
}
/* Styles for buttons within the blog post */
.blog-post button {
background-color: #6c757d;
color: #fff;
}
In this example, the general button styles apply a blue background colour and white text to all buttons and the .cta-button
class. However, the styles for buttons within the .blog-post
class override the general button styles, setting the background colour to a darker grey.
If you want the CTA button to have a different style than the other buttons within the blog post, you can use a more specific selector:
.blog-post .cta-button {
background-color: #007bff;
color: #fff;
}
By targeting the .cta-button
class within the .blog-post
class, you're ensuring that the CTA button's styles have a higher specificity than the general button styles or the styles for buttons within the blog post. This will allow the CTA button to display the desired blue background colour, regardless of the parent element's styles.
Conclusion
Unwanted HTML button background colour in WordPress is often caused by CSS specificity issues. By understanding how specificity works and applying more specific styles to your buttons, you can ensure that your buttons display the correct background colour and align with your desired design.
Remember, the key to overcoming this problem is to give your buttons a unique ID or class and then create a CSS rule that specifically targets that ID or class. This will ensure that your button styles have the highest specificity and take precedence over any parent element's styles.
