WordPress: Elementor plugin is adding <br> in button
You have to assign a custom class tag to the button element, it most likely would be assigned to the div .elementor-button-wrapper, you’ll have to check it with dev tools, then you need to access the theme style on appearance/editor. So you could add the following code:
.class-used br{ display:none;}
In case the class you assigned to the button is not in a parent tag on top of all
you need to eliminate try the same process assigning the class to the column or element that wraps the button. Hope it give you an idea to solve the issue.
