My question is: when i remove the comment tags "" in the html.. suddenly the width of the page is wider than the browser window. Do you guys have any idea how to fix this ? I feel like its some kind of weird error.

here is a jsfiddle of it.. https://jsfiddle.net/4erj4w2p/ – blabla May 16 '16 at 17:43 — blabla, May 16 '16 at 17:43

Here is updated JsFiddle https://jsfiddle.net/4erj4w2p/1/. The problem is your width units - vw (viewport width). It takes into account scrollbar width as well. Please refer to this : Why does vw include the scrollbar as part of the viewport?

First, you have no height in your #rightBlock.. add this:

height: 60vh;

Then, when you add your second section, lowerContainer, you "automatically" creates a vertical scrollbar. Because of your scrollbar, you need more horizontal space to show your content, and that is because your have your horizontal scrollbar.

If you put height = 10vh instead, you won't have any problem.

This is giving extra width because of the 100vw. I updated 100vw with 100% and it is working fine. Please check by updating it.

Also can you please tell me about vw? Is it anything related with px. or just a locale issue??

Uhm.. i have ben using vw and vh( viewport width and viewport height) for some time now and always used to think it was perfect for responsive design. -> http://www.w3schools.com/cssref/tryit.asp?filename=trycss_unit_vw – blabla May 16 '16 at 18:06
