Hi @dsommer,
For the above changes, go to “Dashboard=> Appearance=> Customize=> Theme Options=> Custom CSS” box and add the following CSS.
/* Add background to Header */
#branding {
background-image: url('Put Your Image Link Here');
background-position: center center;
background-repeat: no-repeat;
background-size: cover;
}
/* Change site title's color */
#site-title a {
color: #0000ff;
}
/* Change site description's color */
#site-description {
color: #0000ff;
}
Note: Replace Put Your Image Link Here with your desired image link. Replace the color hex with your desired color.
Regards,
Mahesh
