Is it right to add tag inside tag?

Question

I was wondering if we could add a span tag inside a tag....

Answer 1

While that code is valid, it's not the best way to do it.

Here's your code again, indented for clarity

    
        Dog dresses
    
    

The first thing to notice is you have a trailing
. What's that for? Extra spacing? Well use padding instead!

Secondly, you don't need the span element - the bold style can be applied directly to the tag.

Why not just write it like this:

    Dog dresses
