How to select all anchor tags that open in a new tab using attribute CSS Selectors for target='_blank'?
Jun 30, 2025 am 01:20 AM
If you want to use the CSS selector to select all <a></a> tags (that is, the links to target="_blank" ) that are opened in the new tab page, the method is actually quite straightforward, which is to use the attribute selector.
You can write this way:
a[target="_blank"]
This selector will match all hyperlinks on the page with target="_blank" set. If you also want to add dot styles to these links, such as adding an external link icon or changing the color, you can write it like this:
a[target="_blank"] {
color: red;
padding-right: 20px;
background: url('external-icon.png') no-repeat right center;
}How to confirm whether your selector is effective?
Sometimes you may write a selector but don’t see any effect, which may be the following reasons:
- CSS is not preferred enough : Other styles override your rules, you can try to increase the selector weight or use
!important(abuse is not recommended). - HTML structure problem : Make sure your link does carry
target="_blank"attribute. - Caching issues : Refresh the browser or clear the cache to see if it takes effect.
You can use the browser's developer tools (right-click on the element → Check) to see if the corresponding link is correctly selected and view the style of the application.
How else can I expand this selector?
In addition to exact matching _blank , you can also do some more flexible or complex filtering:
Match all links with
targetattribute, regardless of the value:a[target]
Match the links where
targetvalue contains"blank"(note that this writing may match the case wheretarget="notblank"):a[target*="blank"]
But most of the time, we only need to accurately select links that will actually open in a new window, so the most recommended way is:
a[target="_blank"]
Examples of practical application scenarios
Common uses include:
- Add an icon to the external link to let the user know that this is jumping to another website.
- Change the color of the links opened in a new window and distinguish them from the links in the site.
- Use with JavaScript, for example, add
rel="noopener"to these links to prevent security vulnerabilities.
For example, you want to add rel="noopener" to all external links. Although it cannot be done with CSS, you can combine JS and this selector to do it:
document.querySelectorAll('a[target="_blank"]').forEach(link => {
link.rel = 'noopener';
});Basically these are the operations. This selector is simple but practical, suitable for link style management and behavior control.

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.
