Hi John,
I’m not sure I understood what you mean.
Layout Elements don’t add/create contents as it can only change the layout of a page.
If you want a conditional CSS that matches the same condition as the Layout Element, you can create a Hook element containing the CSS styles you want for it and just copy the Display rule of the Layout element.
Example: adding a padding top and bottom to article of the page.
Add this code to the code area of the Hook element:
<style id="hook-element-styling">
.inside-article {
padding: 40px 0px !important;
}
</style>
and then copy the display rule location of the layout element to this hook element
