Multiple CSS or Javascript Files
In cases where you have multiple CSS or Javascript files, the sequence in which they are included matters. Browsers will load and apply all the included files, overwriting previous styles or Javascript functions if necessary. Therefore, it is generally recommended to place the most important or frequently used CSS or Javascript files first.
Best Practices
In summary, here are the recommended best practices:
- CSS: Include CSS files in the section before any other content.
- Javascript: Place Javascript files before the closing tag.
- Multiple Files: Order the inclusion of multiple CSS or Javascript files based on their importance.

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)?

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.
