HTML 5 Standards - Align Attribute

Question

I have decided to use Sololearn as a refresher course on the concepts of HTML5 and CSS, I have to admit that teaching students the concepts, should be done according to the W3C standards.
Please take note that align is no longer supported in HTML5 - it states to use CSS instead.

here is a link to review and verify
I personally feel, that if this course continues to instruct, the information should be revised to reflect the changes made to instruct students using the correct use of the syntax.

Answer 1

The transition between Html4 and Html5 is still not done ^^
And the SoloLearn Html course is a generic introductive one, in which Html5 is just a final little part...
You're right about deprecated attributes, and some of us continue to say it again and again as soon as we can in answers to this Q&A Discussions section. Unfortunaly, the information in here has no orgaization, and so quickly disappear, and bad advices are still overcoming :(

Answer 2

Yea this really confused me! Is that why it isn't appearing as centered when I load it up? Should I learn how to do this or skip over it? I don't wanna miss anything important but don't wanna have to learn a ton before...
