This Is What Happens When You Forget to Add the CSS Class or ID Selector
As a WordPress developer, one of the most common issues you might encounter is unexpected behavior in your website's design. This can often be traced back to a simple oversight – forgetting to add the CSS class or ID selector when targeting specific elements on your page.
In this article, we'll dive into the importance of proper CSS syntax, explore the consequences of missing selectors, and provide you with actionable steps to identify and fix these issues on your WordPress website.
Understanding CSS Selectors
CSS, or Cascading Style Sheets, is the language used to style and format the content on your WordPress website. At the heart of CSS are selectors, which are the way you target specific HTML elements and apply styles to them.
There are several types of CSS selectors, but the two most commonly used in WordPress are:
- Class Selector: Indicated by a
.
(period) before the class name, e.g., .my-class-name
.
- ID Selector: Indicated by a
#
(hash) before the ID name, e.g., #my-unique-id
.
These selectors are essential for ensuring your CSS rules are applied to the correct elements on your WordPress website.
The Consequences of Missing Selectors
When you forget to include the class or ID selector in your CSS code, you can encounter a range of unexpected behaviors. Let's take a look at a few common scenarios:
Scenario 1: Unintended Styles
Imagine you have the following CSS code in your WordPress theme:
background-color: #f1f1f1;
color: #333;
padding: 20px;
Now, let's say you forgot to include the class or ID selector for this CSS rule. Instead of targeting a specific element, the styles will be applied to all elements on the page, potentially causing unwanted changes to the overall design.
This can lead to a visually inconsistent website, making it challenging for users to navigate and interact with your content.
Scenario 2: Overwritten Styles
In the world of CSS, styles are applied based on the specificity of the selectors. If you have multiple rules targeting the same element, the more specific rule will take precedence.
If you forget to include the class or ID selector, your CSS rule may be less specific than other rules targeting the same element. This can result in your intended styles being overwritten, leading to a design that doesn't match your expectations.
Scenario 3: Difficulty Debugging
When you're troubleshooting CSS-related issues on your WordPress website, missing selectors can make the debugging process much more challenging. Without the clear identification of the targeted element, it becomes harder to pinpoint the root cause of the problem and apply the necessary fixes.
This can lead to frustration, wasted time, and a suboptimal user experience for your website visitors.

Identifying and Fixing Missing Selectors
To ensure your WordPress website's design is consistent and functioning as intended, it's crucial to identify and fix any missing CSS selectors. Here's a step-by-step guide to help you with this process:
Step 1: Inspect the Element
The first step in identifying missing selectors is to inspect the element you're trying to style. In most modern web browsers, you can right-click on the element and select "Inspect" (or a similar option) to open the browser's developer tools.
In the developer tools, you'll be able to see the HTML structure of the element, as well as the CSS rules that are being applied to it. This will help you determine if the class or ID selector is present in your CSS code.
Step 2: Check the CSS Code
Next, review your WordPress theme's CSS code to locate the rule that should be targeting the element you inspected. Look for the class or ID name and ensure that the correct selector is being used.
If the selector is missing, you'll need to add it to your CSS code. For example, if you have the following rule:
background-color: #f1f1f1;
color: #333;
padding: 20px;
You would need to add the class or ID selector to target the specific element, like this:
.my-class-name {
background-color: #f1f1f1;
color: #333;
padding: 20px;
}
or
#my-unique-id {
background-color: #f1f1f1;
color: #333;
padding: 20px;
}
Step 3: Test and Verify
After making the necessary changes to your CSS code, save the file and refresh your WordPress website. Inspect the element again to ensure the correct styles are being applied.
If the issue persists, double-check your code for any typos or inconsistencies in the class or ID names. Remember that CSS is case-sensitive, so make sure the selectors match the HTML class or ID attributes exactly.
Real-World Example: Fixing a "Button to Disappear After Been Collapsed" Issue
Let's take a look at a real-world example of how missing CSS selectors can cause issues, and how to fix them.
Imagine you have a WordPress website with a "Show More" button that collapses additional content when clicked. Your CSS code looks like this:
.bg-showmore-plg-button.bg-orange-button.bg-close {
display: none;
}
However, you notice that the button is not disappearing after being clicked and collapsed. This is likely due to the fact that the CSS selector is missing the class or ID prefix.
To fix this issue, you would need to add the correct selector to your CSS code:
.bg-showmore-plg-button.bg-orange-button.bg-close {
display: none;
}
Now, when the "Show More" button is clicked and the bg-close
class is added to the button, the CSS rule will correctly hide the button, as intended.
By addressing this missing selector, you'll ensure that your WordPress website's design behaves as expected and provides a seamless user experience for your visitors.
Conclusion
Forgetting to include the CSS class or ID selector is a common mistake that can lead to unexpected behavior on your WordPress website. By understanding the importance of proper CSS syntax, recognizing the consequences of missing selectors, and following the steps to identify and fix these issues, you can maintain a consistent and well-functioning design for your WordPress-powered website.
Remember, attention to detail is key when it comes to CSS, and taking the time to ensure your selectors are correctly implemented can save you a lot of headaches down the line. Keep these best practices in mind, and your WordPress website will look and function exactly as you intended.
