Solve the problem of overlapping WordPress sticky head and management bar
In WordPress themes, the sticky head (or fixed position head) overlaps the admin bar. Both use position: fixed; top: 0;
, resulting in visual conflicts. Since the admin bar has z-index of 99999, it usually covers the sticky head of the subject (and vice versa). This article will explain how to solve this problem using CSS (and Sass).
(Note: Some topics use JavaScript to locate sticky elements. If JavaScript continues to update the inline top
properties, the following method is invalid.)
Use CSS to adjust head position
For simplicity, we use the .sticky-header
class to represent elements pinned at the top of the page. You should find the right selector based on your topic. We assume that its top
position value is 0. If the top
value has been offset, the following measurements need to be adjusted.
When the admin bar is visible at the front end, WordPress attaches the .admin-bar
class to the element of the page. (This is usually handled by the
header.php
function in body_class();
.) This class allows us to adjust the top
position of the sticky head.
/* 原有CSS... */ .sticky-header { position: fixed; top: 0; } /* 新增CSS... */ .admin-bar .sticky-header { top: 32px; }
The height of the management bar is 32px, we just need to move the sticky head down. But the problem is that the admin bar height is not always 32px.
CSS for small screens
On screens with widths less than 783px, the management bar height is 46px. We need to modify the code to compensate:
.admin-bar .sticky-header { top: 32px; } @media screen and (max-width: 782px) { .admin-bar .sticky-header { top: 46px; } }
If you prefer mobile-first CSS, use the following code:
.admin-bar .sticky-header { top: 46px; } @media screen and (min-width: 783px) { .admin-bar .sticky-header { top: 32px; } }
Create reusable mixin with Sass
If you build a theme with Sass, we can encapsulate it into a reusable mixin:
@mixin admin-sticky-fix( $offset: 0 ) { $narrow-offset: 46px; $wide-offset: 32px; @if $offset != 0 and type-of($offset) == 'number' { $narrow-offset: $narrow-offset + $offset; $wide-offset: $wide-offset + $offset; } .admin-bar & { top: $narrow-offset; @media screen and (min-width: 783px) { top: $wide-offset; } } }
This mixin accepts an optional parameter $offset
that allows the top
value of the specified element (non-0). If no offset is specified, mixin will assume to be 0. If you manually specify $offset
, the @if
condition will modify the default management column height value.
How to use:
.sticky-header { position: fixed; top: 0; @include admin-sticky-fix; } .sticky-header-offset { position: fixed; top: 20px; @include admin-sticky-fix(20); }
Conclusion
Through the above code snippet, the conflict between the sticky head and the WordPress management bar can be easily solved. Sass mixin improves the reusability of the code.

Use WordPress testing environments to ensure the security and compatibility of new features, plug-ins or themes before they are officially launched, and avoid affecting real websites. The steps to build a test environment include: downloading and installing local server software (such as LocalWP, XAMPP), creating a site, setting up a database and administrator account, installing themes and plug-ins for testing; the method of copying a formal website to a test environment is to export the site through the plug-in, import the test environment and replace the domain name; when using it, you should pay attention to not using real user data, regularly cleaning useless data, backing up the test status, resetting the environment in time, and unifying the team configuration to reduce differences.

When managing WordPress projects with Git, you should only include themes, custom plugins, and configuration files in version control; set up .gitignore files to ignore upload directories, caches, and sensitive configurations; use webhooks or CI tools to achieve automatic deployment and pay attention to database processing; use two-branch policies (main/develop) for collaborative development. Doing so can avoid conflicts, ensure security, and improve collaboration and deployment efficiency.

The key to creating a Gutenberg block is to understand its basic structure and correctly connect front and back end resources. 1. Prepare the development environment: install local WordPress, Node.js and @wordpress/scripts; 2. Use PHP to register blocks and define the editing and display logic of blocks with JavaScript; 3. Build JS files through npm to make changes take effect; 4. Check whether the path and icons are correct when encountering problems or use real-time listening to build to avoid repeated manual compilation. Following these steps, a simple Gutenberg block can be implemented step by step.

In WordPress, when adding a custom article type or modifying the fixed link structure, you need to manually refresh the rewrite rules. At this time, you can call the flush_rewrite_rules() function through the code to implement it. 1. This function can be added to the theme or plug-in activation hook to automatically refresh; 2. Execute only once when necessary, such as adding CPT, taxonomy or modifying the link structure; 3. Avoid frequent calls to avoid affecting performance; 4. In a multi-site environment, refresh each site separately as appropriate; 5. Some hosting environments may restrict the storage of rules. In addition, clicking Save to access the "Settings>Pinned Links" page can also trigger refresh, suitable for non-automated scenarios.
