Determining Bootstrap Popover Width
In Bootstrap 3, the width of popovers is constrained by the available space within the triggering element. This can lead to popovers appearing too narrow when using wide input elements like the form-control class.
CSS Width Modification
One method to increase the popover width is through CSS:
<code class="CSS">.popover{
max-width: 100%; /* Max Width of the popover (depending on the container!) */
}</code>
This sets the maximum width of the popover to 100% of the available space within its container.
Container Specification
If CSS width modification is not effective, it may be necessary to specify the container element for the popover:
<code class="JS">$('[data-toggle="popover"]').popover({
container: 'body'
});</code>
This instructs Bootstrap to contain the popover within the body element, rather than the triggering element. This allows the popover to extend beyond the input element.
Container Relevance
The width of a popover is determined by the following factors:
- Max Width: Defined by the max-width CSS property or by JavaScript.
- Container Width: The width of the container element specified in the JavaScript configuration.
In this case, the container width is set to 100% of the body, allowing the popover to stretch across the entire screen.
JSFiddle Demonstration

By adjusting the max width of the popover and specifying the container element, you can achieve the desired popover width.

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.
