Broken HTML has been detected in your theme's code.

[NicolaRowlands]

I'm a total novice with code which is why I chose shopify and a theme that was easy to use. The banners on my homepage all seem to have enlarged beyond the size they should be, from no fault of my own, and I don't know how to rectify this! Can anyone help? In theme settings it just says 'Broken HTML has been detected in your theme's code.'

What theme are you using and what's the address of your store? If you have a storefront password set under Online store >> Preferences, please post that here too or disable it, otherwise we can't see your storefront. (NOTE: Do NOT post your admin password here, only the storefront password).
