I’m not the designer of the template but I can still help you out.
The mobile menu displays exactly what is shown in the desktop view, I resized the browser and also viewed it on my iPhone. What’s supposed to be missing?
I’m going to have to use bullet points below because there’s a lot to cover;
• Container slide currently has a relative position of top left 40%, this means it’s being pushed down. Change it to TOP and 30%.
• In tablet view, your hero heading line height is 98px, reduce this to 70px.
• In landscape view, the hero heading has a -60px margin, change it to 0px, reduce the line height to 55px and reduce the top margin to 0px.
• In mobile view, add 10px padding to left and right of the container slider so your text doesn’t display to the edge of the screen, reduce the hero heading font size to 25px and 40px line height.
