Nowadays, people are browsing the web on screens of all shapes and sizes. You need to make sure that your website is responsive for people on large desktop computers as well as those on phones and tablets.
One of the key parts of a website launch checklist is checking how your website looks on various devices. You want to make sure that navigation bars, forms, and interactive features are all appearing exactly as they should be.
Many website builders create responsive website designs as standard nowadays, but if you've had your site manually built, it is extra important that you carry out thorough checks.
A good way to do this is through
Google's Device Mode. They have a handy guide which runs you through the process, letting you see how your website looks on varying screen sizes.
