Mobile fiew wrong if content stars on top (behind menu)

Hi, I added the following to css (to make sure the page starts on top behind the menu):

#content.site-content {
    margin-top: -100px;
}

desktop version looks fine, but on mobile the frist section moved to the right. Any idea whats wrong?

Hello Vossmann,

I have just inspected your website and it looks like slider plugin issue.

Can you please try to contact that plugin support and see what they say?

Kind Regards, Roman.

it’s also if i replace the silder with a simple picture plugin… I think its because i addede the code. i’m sure i’ve done this in the past with another code, but i can’t remember. May you have an idea whats the best way to start the content on 0 and not -100px to have full screen picture behind the menu bar.

Hello Vossmann,

As an option, you can try to make your menu Sticky in Customize → Header area → Menu style section instead of using that CSS code.

Kind Regards, Roman.
