I am having trouble customizing my SharePoint site. I want to add multiple webparts side by side on my page but SharePoint doesn't have this option natively. You can only add them in the downward direction not to the left or right. I already saw a similar question like this and it mentioned adding code using SharePoint Design.
I am very new to SharePoint and I don't understand how to add this specific code. I will link the question as it is very much similar to my ordeal.
This is the same question link: How to have two web parts side by side in same zone
I am using SharePoint Online. And I know how to use spfx webparts. If there is a webpart that can accomplish this please link it.
