I am using Sharper OnePage template Joomlña 4 and I try to change the menu backgroud color and make 2 lines in ti, but when I load the page apears in blac and 2 lines it's ok, but when I go down in page, then the background color change to the correcty color but the two lines insert spaces.
Also in a text block I edit and put some words in bold but do not display in bold.
