As developers, we often forget to do the final polishing after we're ready to deliver the code. This checklist will remind you about 88 things that are important for any web application to check and implement. Contains tips about HTML, fonts, CSS, JS, images, accessibility, performance and SEO. If we all took the time and effort to check off even 10% of the list, it would be a huge improvement. This is especially important for freelancers who care about delivering high quality products to clients. After all, excellence is a habit, not a skill :)
