Why do I get an error on W3C Test when I set the h1 from 100% to 90%? Whenever I change the %, an error appears. _Error: Element h1 not allowed as child of element span in this context. (Suppressing further errors from this subtree.)_ _From line 130, column 488; to line 130, column 491_ _9\_page10’\>_ ---

Here is the link. When I set it to 100% the error disappears… [http://piranha-ag.ch/](http://piranha-ag.ch/) ---

The only guess I can make right off the top of my head is this. The h1 tag by definition is the largest most important element on the page. Making it 90% makes it appear to be less, even if it isn’t. ---

Thank you. But it also appears if I set the text to 90%. No matter on which Text I use it, an error appears. ---

Something is definately wrong with stacks. When I ajust the text without stacks, no error appears. ---

We would need a link to a page when it’s **broken**. Then link above is after you set it back to 100%. Also might help if you gave us what stack(s) your using and how your changing the size. ---

I took a quick look at your site. The syntax error I’m seeing is related to a text stack that has a` ` in it to set the font size to 110%. It then has an unordered list within the span. Don’t know how you’re setting the 110% but you’re not suppose to have a UL within a span. ![2017-09-25_12-28-28](https://europe1.discourse-cdn.com/flex005/uploads/realmacsoftware1/original/2X/d/daf4b6682ebdf193e4e71af3974520139e8e733a.png) ---

Hi Doug, thank you. This is cliear so far. But why can I change the text everywhere but not the list? ---

You can change it just not with a `` element. From an HTML prospective you could use a `
` or a `
` to wrap your list to apply the class, you can even put the class on the `
    ` tag. The span element is an inline element, intended to be used within a paragraph or header, not to contain block level elements. You could use a span for a list but would need to apply it to **each** bit of text `
  • ` within the list `
      `.
