Backgrounds on Weebly themes can be changed in a few simple ways. First, go to the Theme Settings page and under the General tab, find the Backgrounds section.
There, you can select from a variety of background images to use as your theme’s background. You can also choose to use a custom background image, if you have one saved.
To change the background on your site, first click on the Background image link in the Backgrounds section of the Theme Settings page. This will open a new window where you can select the background image you want to use. Once you’ve selected the image, click on the Copy link to copy the image to your clipboard.
Next, go to the Site’s header (usually in the top left corner of your site), and paste the image into the desired location. Click on the Update Background button to apply your new background image to your site.
Finally, if you want to change the background color of your site, you can do this by going to the Site’s header again, and under the Colors section, selecting a new color from the color picker. Click on the Update Background button to apply your new background color to your site.
