Background image issue

Hi .I’m creating a website.
Its background image is included on the entire page.
When I exported the Imeg from Figma, its sign was 24. It could not be inserted into the webflow.
The quality decreases when one compresses and inserts.
And when the image is finished, the content jumps out. What can be done about this?

Here is my site Read-Only: [LINK](Webflow - Venusian 6th)

Don’t set the background image to the Body tag. Instead, add a div, set a background image to it, and then add elements to that div.

It should look like:

 <div class='background-image'>
