Sections disappear below 430px | Preview does not reflect actual spacing for published site

Hi,

Thanks very much for responding @maksymz

I’ve restarted the build process (https://akroots.editorx.io/website) to try and use pixels for sizing rather than VH. All was going well structurally (fonts etc are yet to be dealt with) but all of a sudden the footer appears in the middle of the page on screens below 430px. Please could you help me to understand why this is, and suggest how I might fix it?

Your help is much appreciated in this. Thank you!

Joel
