html – Centralize and stretch the section of a website with w3.css

Hello Good afternoon everyone.

I need your help about w3.css.

My questions are:

  • How do I centralize the Work Experience, Education and Skills sections in the middle of the browser window?

  • How do you fix datetime on the same level as the timebar, ie on the same line as the timebar?

  • And how to stretch the footer bar to occupy all the width of the browser window?

I would appreciate your support, please.
