Valid HTML5 code

[davy_yg]

Hello,

I would like to check if my HTML code is valid for international standard or not. Is there any machines that can check that?

Evenif there is no error in it - I need to make sure if I use a valid and clean code.

Any recommendation?

Thanks in advance.

Thanks for advice.

Is <center> element obsolete? So I have to use <div style="text-align: center"></div> instead?

[davy_yg]

Is it possible to define center through css and use it in html/php ?

Since your other questions are about bootstrap, it includes:

class="text-center"
