I was trying the grid examples given on Bootstrap page when I found that the clearfix reset pulled my grid into an "xs" setting even when the browser window was resized to "lg". Below are a few screenshots with the clearfix set and browser maximized to full width and height showing the difference between Bootstrap 3 and Bootstrap 4:
Bootstrap 3:

Bootstrap 4.0.0 alpha:

Could you post a JSBin/JSFiddle of this?
Also, what browser and OS are you using?
Hi @VishalSubramanyam!
You appear to have posted a live example (https://fiddle.jshell.net/vishal_subramanyam/cspveff6/show/light/), which is always a good first step. However, according to Bootlint, your example has some Bootstrap usage errors, which might potentially be causing your issue:
.rows that were not children of a grid column or descendants of a .container or .container-fluidYou'll need to fix these errors and post a revised example before we can proceed further.
Thanks!

This is my JSBin after revision with Bootstrap 4:
https://jsbin.com/jajirudepu/1/edit?html,output
I am using Chrome on Windows 10
.visible-xs was removed in v4. See http://v4-alpha.getbootstrap.com/migration/#responsive-utilities. You should use a .hidden-*-up and/or .hidden-*-down class instead. These classes hide the element at the given breakpoint and all sizes "up" (larger) or "down" (smaller).
Note: v4 adds an new breakpoint. Therefore, you should use one breakpoint larger than you would in v3 for all grid sizing.
Closing per @RyanZim. Let me know if there's something I'm overlooking.
