Jumbotron Image

My site looks stupid at the moment. Jumbotron image set to 1980 x 1080 but on my laptop it doesn’t fill the width so I have a white boarder, which would be ok but the page links at the top are white and therefore not visible and the Site Title spills out of the image. What resolution do I need the image or how do I fix it?!!

Hi there,
Thanks for reaching out.
In reference to your query here, that image seems to be a full-width from my end and no border is rendered. Attached is a screenshot. Could I possibly bee missing out on something here?

I look forward to your reply.
Best Regards,
Support.

Because I added this:

#header.header-front-page {
background-size: 100% !important;
}
