Header and Mobile

Good Morning,

Thank you for the amazing theme, I’m new to WP and could really use some assistance with 2 issues.

I need some help in regards to the Header, what is the recommended size? When I upload the image its to large and its not centered?
When I look on the mobile version the Header and Footer are out of proportion? Website is http://langebergteels.co.za

Thank you for the assistance

Hello there,

I hope you are doing well today.

Have you added any CSS code to the theme? If so what was that code?

Best Regards,
Support

Thank you for getting back to me so quickly.

I have added CSS code to the theme but mainly for other issues I had.
Pls see attached screen shot!

I seem to have sorted the header out but am still struggling with mobile version, could I pls get some assistance?
The mobile site doesn’t fit on screen?

Thank you
