Bootstrap basic question?

Hi guys,

I’m studying bootstrap and I have this page below,

My question is why it won’t flex?

Can someone please help me fix this.
Thank you very much in advanced.

It does flex at certain sizes (when the browser is narrow) but at larger widths you jump between states because you have fixed px widths set on the containers. E.g.

@media (min-width: 1200px)
.container, .navbar-static-top .container, .navbar-fixed-top .container, .navbar-fixed-bottom .container {
width: 1170px;

To be honest, this is a good advertisement for not using frameworks. The page is already a mess, and there’s harly any content on there. It would be better to code this from scratch, in my view, using just the code you need, rather than tryng to deal with a ton of code you don’t need.
