A reader recently posed a great question: how can we obtain a browser's complete list of valid CSS property values? While we can determine if a property exists (e.g., cursor
), finding all acceptable values for that property presents a challenge. CSS specifications offer a list, but this might not be exhaustive; browsers may support additional, undocumented values.
We can test values empirically by applying them to an element and inspecting the result in browser developer tools. However, this requires manually testing numerous possibilities, making it inefficient. The CSS.supports(property, value)
method helps, but it only confirms support for a specific value, not the full range of possibilities. Ideally, a function like CSS.validValues("property-name")
would return an array of valid value types (e.g., ["

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.

The HTML popover attribute transforms elements into top-layer elements that can be opened and closed with a button or JavaScript. Popovers can be dismissed a number of ways, but there is no option to auto-close them. Preethi has a technique you can u

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.
