Hello!

We really like your project but we recently realised that your website is not very accessible. It is missing button names, input labels, image alt texts etc. We have made an attempt to add some button names as well as svg titles, however we are not able to run the site as your readme doesn't indicate how. We present you with a first pull request, hoping that we will be able to work with you more in depth if you are interested.

Best regards, Titika Apostolaki, Enrica Garcia, Natalia Blanco
