To less place in gallary . can`t change color or photo for topbar

Hello @rulu00,

To change the color for topbar, follow the below steps:

Go to Dashboard >> Customizer >> Additional CSS >> Paste the below CSS code >> Publish. It will change the size of the logo on the home page.

.top-info {
background: add your color code here;
}

and you can add photo for topbar and header by header image option

Go to Dashboard >> Customizer >> Header Image >> Add New Image

Thanks.
