Question

here is the code

<div id = "content">
  <div id = "text">
    <h1>Text</h1>
  </div>
</div>

I’m a newbie and I would know if it is possible, using css, that I can apply a style only to that h1 element inside those div without any other h1 out of those div could be feel the style.

Answer 1

Yes, you can:

div#content > div#text > h1 { some style here }

In this case you will touch only h1 which is placed in hierarchy like you described.
