CSS Validation
CSS validation is the process of checking code against the formal guidelines and standards set by the World Wide Web Consortium (W3C) for CSS documents.
Validating a website has several specific benefits, including:
- Cross-browser and cross-platform compatibility: Validated web pages are more likely to be compatible with different web browsers and platforms, ensuring consistent rendering across devices.
- Search engine visibility: Standards-compliant web pages have better visibility to search engine spiders, increasing the likelihood of appearing in search results.
- Error reduction and accessibility improvement: Validation helps reduce unexpected errors and makes web pages more accessible to visitors.
Common errors identified by the validator include:
- Block-level elements as children of inline-level elements.
- Images without alt attributes for descriptions and accessibility.
- Deprecated tags.
- Anchor tags without title attributes.
When developing a website, it's important to consider these points. You will gain a better understanding of the errors and warnings by developing a site and then using the validator.
Note: Validation is important to ensure consistent interpretation of web pages by various web browsers, search engines, and users, aligning with your intended presentation and functionality.
