If symantic HTML is more readable by the browser and makes it easier to understand html content then why learn div’s in the first place? Why not just learn symantic HTML from the outset?


Hey @stevesmith1802631825!

So if I understand correctly, your question is why do we learn divs when we are taught that header and nav are better to use.

I would say that the reason for this is because many people still use div instead of semantic HTML, so it is good to have a familiarity with divs

Hope this helps!


Ok that makes perfect sense, I also just learnt that this is a new feature in html5 which would back up your theory as I imagine there are a lot of people out there who may not be familiar with the use of Semantic html or have used div’s on their sites that were built before html5.

Many thanks for your reply and help.

It would be great help if someone could clarify the difference between HTTP GET AND HTTP POST.
I am confused because as per w3(https://www.w3schools.com/tags/ref_httpmethods.asp) GET is used to request data from a specified resource. , but while submitting form we are sending data (submitting) instead of getting.
So why aren’t we using POST instead of GET??


While the course is discussing client-side validation, one of the use cases is “This can also help us protect our server from malicious code or data from a malicious user.”

Unfortunately, this is incorrect, and might give people the wrong idea (i.e. that client-side validation has use as a security measure).
All of the other examples are correct though, but I heavily recommend that this one gets reworded or deleted, as relying on client-side validation for any security will lead to issues.
