First, go to the Divi Theme Options panel and click on the Blog Layout tab. In the Blog Layout section, you’ll see a list of available layouts.
You can select which one you want to use by clicking on the choose button next to it.
Once you’ve selected your layout, all you need to do is customize it to your liking. You can change the size of the blog posts, the font size, and even add some custom CSS code if you want.
Finally, make sure that you save your changes by clicking on the save button at the bottom of the Blog Layout section.
