Should You Use Custom HTML Tags for Semantic Clarity?

Using Custom HTML Tags for Semantic Clarity

Custom HTML tags, such as "", offer a tempting option to create unique identifiers. However, their use raises questions about semantic correctness.

According to some, this approach is inappropriate, as HTML tags should adhere to established conventions. Heading tags like "

" are specifically designed for structural markup, while custom tags lack such semantic meaning.

However, others argue that in the evolving landscape of HTML5, innovation is crucial. As browsers implement specifications at varying paces, there is no definitive standard for "valid HTML." Nonetheless, caution must be exercised.

If you choose to utilize custom tags, carefully consider the name to avoid potential conflicts. Additionally, to ensure compatibility with Internet Explorer, JavaScript can be employed to create the elements dynamically.

Current trends indicate a preference for custom elements with a "-" in the name, such as "x-toys" or "my-toys." This convention is intended to differentiate custom elements from standard HTML tags.

Ultimately, the decision of whether to use custom HTML tags is a matter of balancing flexibility and semantic correctness. While caution is advisable, innovation can be beneficial in the context of LANs, login-protected pages, or projects with frequent updates.
