Great job Jemima, but that being said you shouldn't only trust in the lighthouse! Actually, I find several issues on your website! For example the "iframe loading" is not supported by the Firefox and Safari prove: https://caniuse.com/?search=iframe%20loading The "meta theme color" almost only support on Chrome (so your multiple color themes is useless at this point!) prove : https://caniuse.com/?search=theme-color Scripts are not minified!
