Really enjoyed evangelising UmBootstrap and Block Grid at @UmbKent. @Mike Masey raised a good question regarding responsive images in different areas in Block Grid which I have not implemented in UmBootstrap but have done so in client sites by serving a different srcset based on the number of columns used by an area. Here is an example, but of course there are many ways to acheive this. https://cdn.discordapp.com/attachments/1184134344772685944/1277909618760351797/image.png?ex=66cee193&is=66cd9013&hm=8cae215729fbb5d3fd838a79c23d22b533c7fe7d25a37041969ed5345a3ade7a&
