If you followed the same instructions as the user in the other thread, this custom CSS should push down the title so it doesn’t cover the menu:
.post-thumbnail + .entry-header {
margin-top: 0;
}
Don’t edit the theme files directly, otherwise your changes will be overwritten whenever the theme is updated.
An easy way to add custom CSS is to install the Jetpack plugin and activate the Custom CSS module. You’ll then add your custom CSS in the new stylesheet editor that’ll appear in your dashboard, under Appearance > Edit CSS.
As alternatives, you could either install a standalone custom CSS plugin, or create a child theme.
If you still need help, please provide a link to your site so I can take a look directly – thanks!
