To change the canvas size in Webflow back to the default 1165px x 100%, you'll need to follow a few steps. Here's how you can do it:
1. Open your Webflow project and select the page you want to change the canvas size for.
2. In the Designer panel on the right-hand side, click on the settings icon (the gear icon) next to the Canvas Width field.
3. A dialog box will appear with the current canvas size settings. By default, Webflow sets the canvas width to 1165px.
4. Change the numerical value in the Width field to 1165. Ensure the unit is set to "px" for pixels.
5. You can leave the Height field set to "100%" if you want the canvas to take up 100% of the available vertical space.
6. Click "Apply" to save the changes.
After following these steps, your canvas size should be reset to the default 1165px width and 100% height.
It's worth noting that if you're experiencing a different canvas size of 993px x 100px, it might be due to some custom styling or changes you made. Make sure to review any custom CSS or positioning properties that might affect the canvas size to ensure it's back to the default. If you're still encountering issues, you can reach out to Webflow support for further assistance.
