One of the things we always recommend, especially if you are planning to make a customization of your Weebly theme, is to take a backup of the theme itself.
Please note, we are not talking about taking a backup of your entire website, just the Theme that you've got installed on your Website in the Weebly Dashboard.
You may even want to do this if you're using a standard weebly theme.
The reason you might want to do this is because, if you are making a custom change to your Theme and are not 100% confident the changes you're making will work, a backup will give you a working version you can revert to if you accidentally cause an issue or break something. It's so much easier to restore to the last known working version than trying to undo any changes you've made.
Remember, taking a backup is totally Free, and takes a matter of seconds. If you do it regularly you won't run into frustrations if something goes wrong.
Taking an export (or backup) of your Weebly theme couldn't be easier. just follow these two simple steps
1. Go to the code editor Click on Themes > Edit HTML / CSS
2. click "export theme" The file will then either automatically download to your "downloads" area or you'll be asked where to save the file on your computer..
