Deploying the theme

Hello,
This theme not responsive – not looking good on mobile. I’m using your recommended feature slider image dimensions yet it doesn’t come out well on mobile. Is there a way you can make the text come a little lower on the home page so it doesn’t sit on the head of my hero image?

2. How do I take out the pages I don’t need? I have tried to unpublished them ( set to private) but this is still not working. Pages I don’t need for now – gallery, service,

3. Created a new ‘about’ page and published. but still not showing on my website. I have deleted your templated about pages but the new page still not showing. Could you please help?

4. After using your recommended image dimensions for the header image of inner pages, it does not deploy correctly. Image too large making page headers hard to see and too low down on page. Could you also help with this?

Thank you
