Highlight Image Input ``` --- ## Technical Considerations & Best Practices ### 1. `:image` vs. `` It is important to distinguish between `` and the standard HTML `` tag: * `$(":image")` **only** selects `` elements. * It does **not** select standard HTML image tags (``). To select standard images, use the element selector `$("img")`. ### 2. Performance Optimization Because `:image` is a jQuery extension and not part of the official CSS specification, queries using it cannot take advantage of the performance boost provided by the native DOM `querySelectorAll()` method. To achieve optimal performance, especially in modern browsers, it is recommended to use standard CSS selectors instead: ```javascript // Recommended for better performance: $("input[type='image']") ``` This standard attribute selector is equivalent to `$(":image")` but runs significantly faster because jQuery can delegate the query directly to the browser's native rendering engine.
