Are nested span tags OK in XHTML?

Will this validate in XHTML?

<span>hello<span>world</span></span>
Solution

  • Yes it will. You can help yourself by using the w3's validator direct input option:

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
      <html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
        <head>
          <title>Title</title>
        </head>

        <body>
           <p>
               <span>Test<span>Nest span</span></span>
           </p>
        </body>
      </html>
