CSS & Customization help needed.

Hi,

I need some help with the customization of the theme and with CSS as well.

1: In “About Us” section – I don’t want to show the “skills widget” – how can I do that? Or can I use any other widget there instead of skills widget?

2: In “Full Width” section – I just want to show the customer support and social icons. How can I align both in the centre?

3: In designing pages for instance my “About Us” page – there’s already a header image – how can I change that image?

Thanks & Regards,
Rashida H.
