All Ads in Space (Grid System)

There are a few reasons to use a grid system for ads:
1. It helps to keep the ad sizes consistent, which makes it easier for advertisers to create ad campaigns that will work across multiple platforms.
2. It can make it easier to track ad performance, since all of the ads will be the same size.
3. It can help to create a more uniform look for an ad campaign, which can be helpful for branding purposes.
