Wails desktop application: Resolve third-party skin CSS coverage conflicts

When building Wails desktop apps that support third-party skins, it is crucial to ensure that custom CSS can correctly override the default style. This article will explore how to resolve common problems in the failure of third-party skin CSS to take effect, and the root cause is the CSS selector weight conflict.

Many developers have found that even without scoped and !important , the styles of third-party skins are still covered by the styles of the application. This is due to differences in weights of CSS selectors.

Workaround: Simplify the CSS selector

Reducing the CSS selector weight is the key to solving the problem. The deeper the selector level, the higher the weight. For example, .navbar .navbar-nav .nav-link has a higher weight than .navbar .nav-link . To cover the former, third-party skins need to write higher weight selectors, which adds complexity.

For complex components, such as Element UI<tabs></tabs> Components, whose selectors can be very verbose (e.g. .el-tabs--border-card > .el-tabs__header .el-tabs__item .el-tabs__item ), are very difficult to directly cover.

Best Practice: Simplify CSS Selector

To ensure that the CSS of third-party skins can be effectively covered, developers are advised to follow the following best practices:

• Keep the selector level shallow and short: minimize nested levels in the selector and reduce the selector weight.
• Use more specific class names: Add more specific class names to elements that require custom styles, rather than relying on common selectors.
• Avoid overuse of wildcards: Wildcards (*) will match all elements, increase the weight of the selector, and should be used with caution.

By simplifying CSS selectors, the possibility of weight conflicts can be reduced, thereby effectively improving the coverage of third-party skins and simplifying the development and maintenance process. A reasonable CSS selector design is the key to ensuring that third-party skins work properly.
