You could upload an image logo for the header, loading, and footer in SEA Theme > Theme Options > General Settings. The custom logo is limited within 120px height by default, and you could set the height for Desktop and Mobile layout. The custom logo supports JPG, PNG, GIF, and SVG format. The SVG Support plugin should be installed if you use SVG logo.
If you want to set plain text logo, please activate “Enable Plain Text Logo” to set.
If you want to show a different color logo on particular pages, please upload the logo from “Alternative Image Logo”.
