Can I Put `` Tags Inside the `` Section of My HTML Document?

Embedding Tags within

HTML 4 dictates that tags should be placed within the section. However, most browsers permit their inclusion within the element.

Historically, this practice was considered poor programming style. However, the introduction of the scoped attribute in HTML 5 allows for the creation of stylesheets scoped within the parent element of the tag. This enables tags to be placed within the element, providing certain limitations are adhered to.

Case Study: Scoped Style

Consider the following HTML code:

In an HTML-5 enabled browser supporting the scoped attribute, rendering this code results in the scope of the stylesheet being limited to the element. Caveat: Lack of Scoped Attribute Support

It's important to note that as of May 2013 (the time of writing), no mainstream browser supported the scoped attribute. However, developer builds of Chromium supported it.

Implication: Future-Proofing and Current Browser Behavior

Despite the lack of support for the scoped attribute, current browsers generally permit tags within the .

Given the fact that:

Scoped attribute is ignored by most browsers tags within are allowed by most browsers Future implementations must allow scoped tags within It is essentially harmless to place tags within the , provided they are future-proofed with the scoped attribute. The only drawback is that current browsers will not scope the stylesheet.

Conclusion

Embedding CSS within HTML is a convenient way to achieve specific stylings for encapsulated, modular components. While the practice was once considered poor style, the scoped attribute in HTML 5 provides a legitimate solution. However, it is essential to be aware of browser support limitations and future-proof code accordingly.
