Altering CSS Rules Dynamically with JavaScript
Manipulating CSS rules dynamically from JavaScript offers remarkable advantages, enabling the modification of the visual appearance of web elements on-the-fly. This is particularly useful for customizing the user experience based on user interactions.
Changing a Rule-set Based on Widget Click
To achieve this modification dynamically, you need to access the CSS rule-set and modify its styles. Here's how you can do it:
-
Obtain References to the Rule-set and Style Sheet:
- Utilize the document.styleSheets property to retrieve an array of all stylesheets linked to the document.
- Use the cssRules property on the obtained style sheet to get an array of rule-sets.
- Locate the specific rule-set by matching its selector with the target element's class name.
-
Modify the Rule-set:
- You can now modify the rule-set's CSS properties using standard JavaScript syntax.
- Set or change the desired style attributes to update the appearance of the targeted elements.
-
Listen for the Widget Click Event:
- Attach an event listener to the widget that triggers the desired appearance change.
- When the widget is clicked, execute the JavaScript code to modify the rule-set dynamically.
By following these steps, you can dynamically alter the CSS rule-set of multiple elements with a specific class, allowing for customized visual changes based on user interactions.

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

CSS: When Does Case Matter (and When Doesn't)?
Jun 19, 2025 am 12:27 AM
In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
