I try building the demo html code as shown below.

It's showed with real width: 1170px. https://gyazo.com/0e13b41b6c619b8efb7a26e2e1b87922
But, when I try adding into view (_Layout.cshtml) in ASP.NET MVC project. Container's width looks like smaller than 1170px. https://gyazo.com/9fe838a4a0ed22f47eb0a96986747e83
Thanks for helping (bow)
Edit 1: This problem only occurs when I use Chrome browser.
Edit 2: I found out the way to fix this issue. You just need uninstall Chrome and reinstall. (I thinks It doesn't relate to Cached, cause I remove all before) Anyway, thanks you guys so much. (bow)
