Hi @fatoo,

Sorry for a late response, I apologize for that.

Sorry, I didn’t both questions, can you explain a little bit more about the questions? I didn’t understand which semi-transparent bar and also, the semi-transparent jumpotron image you’re saying.

Please give us your website’s URL and the website you referenced in the screenshots.

Let us know,
