Remove header image (have tried everything)

I have tried everything. I do not really know css.

I just want to remove the header image because I cannot get photos to look clean and focused once uploaded. It currently just a white screen

What is the css code to add in to remove the header on the about/contact pages/blog pages of my site.

Thanks in advance

Hey there,
Hope you’re doing well today

If you’re having issues with your images being clear, then you may be using pretty small images.

Could you add an image so that I can have a closer look at what’s happening and provide a solution to the images issue? I’m pretty sure you’d like to have beautiful images on your site.

For now, however, you can add and save the following CSS to Appearance > Customize > Additional CSS: {
    display: none!Important;

I hope this helps,

Best Regards,
