A while ago i read a post

"if your page/app don't take care about accessibility it is not a missing feature it is a bug"

At the moment i work on a lot of projects. Also on the webpage rework of the company i am working at.
I want to do some seo stuff and i want to make the page usable for every human.

My problem: i can't find any good resource to learn where i have to put a alt text and how i have to write it. What are the std's to implement it for everyone. Would be great if someone could help me out! :)

Let's make the internet a better place together!<3
