Hi Joel.
Thank you very much for your answer. =)
I will implement the section tag in my code. I think you are right on that and I got it now. I am still having problemas implementing semantics for some reason.
I forgot to ask.. Do you think I used BEM correctly?
Another question I have is related to the tags <button> and <a>. Because I did a bit of research and that is the reason why I chose the tag <a> instead of <button>.
They say the <a> should be used when the button is a link to the content of the page or external content.
And the <button> should be used to create buttons on the page, like when you need an action like onClick().
I took this info from a medium article and that is why I went for the <a>.
Maybe I should have added a role attribute to specify that was a button, because this "learn more" will probably lead to another page or even to another part in the same page, right?
Another thing is I always thought we should start a heading tag with <h1>. Is there a place from where you took this info that I could also read? Because I know they are important from SEO.
I also have difficulties while using these heading tags that is why I ask.
I really appreciate your help. Obrigada. =)
