Why is my Bootstrap Modal Appearing Behind the Background Overlay?
Dec 19, 2024 pm 06:56 PM
Bootstrap Modal Hidden Under Background
Issue:
Despite following the official Bootstrap documentation, a modal is appearing beneath the background overlay, preventing interaction.
Reproducing the Issue:
The code for reproducing the problem is similar to the example below:
<body>
<p>Lorem ipsum dolor sit amet.</p>
<div class="my-module">
<div class="modal fade">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-body">Modal</div>
</div>
</div>
</div>
</div>
</body>
Root Cause:
The modal container (with the "fade" class) can become hidden when it has a non-default position, such as fixed or relative. This issue occurs when the modal container or its parent elements are positioned differently.
Resolution:
To fix the issue, ensure that the modal container and its parent elements have the default position. There are two approaches to achieve this:
-
Move Modal Outside Positioned Elements:
- Relocate the modal div outside any elements with special positioning (e.g., before the closing tag).
-
Remove Position Properties:
- Remove the "position" CSS properties from the modal container and its ancestors until the modal becomes visible. However, this may affect the page layout and functionality.

How can I include CSS only on some pages?
Jun 11, 2025 am 12:01 AM
There are three ways to selectively include CSS on a specific page: 1. Inline CSS, suitable for pages that are not frequently accessed or require unique styles; 2. Load external CSS files using JavaScript conditions, suitable for situations where flexibility is required; 3. Containment on the server side, suitable for scenarios using server-side languages. This approach can optimize website performance and maintainability, but requires balance of modularity and performance.

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.
