Hi there,
That is actually correct. If you add an h1 tag inside the text element you will not be able to change the line height and letter spacing and something like those options.
The reason is that all those options are applied to the wrapping div tag of the text the text element. But you used an h1 so the final code is:
<div class="el131 x-text">
<h1>hello</h1>
</div>
The changes are applied to x-text
element, but the h1 tag has its own CSS from the theme itself. As the CSS of the theme is directly pointing to h1 it will have priority over the wrapper styling.
For such cases, you will need to use the headline element which will do the trick for you.
Thank you.
