Locating an Element by CSS Class Using XPath
Within the realm of webpage manipulation, encountering divs bearing specific CSS classes is a common scenario. To effectively pinpoint such elements, XPath serves as a powerful tool. The query "*[contains(@class, 'Test')]" aims to locate all elements possessing the class "Test," ensuring flexibility in matching various scenarios.
For a more focused approach, specifically targeting div elements can enhance efficiency. The XPath expression "http://div[contains(@class, 'Test')]" achieves this. However, in cases where the class attribute may contain additional values, refining the query becomes necessary.
To ensure precise identification, concatenated strings can be employed. The modified XPath "http://div[contains(concat(' ', @class, ' '), ' Test ')]" verifies that the string "Test" appears within the space-delimited class attribute, preventing partial matches.
Additionally, the "normalize-space" function can be incorporated to eliminate potential whitespace inconsistencies. The expression "http://div[contains(concat(' ', normalize-space(@class), ' '), ' Test ')]" offers further assurance of accuracy.
Remember to replace the "*" with your desired element tag in XPath expressions to avoid unnecessary searches. By utilizing these techniques, developers can effectively locate elements based on CSS classes with pinpoint precision.

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.
