Bootstrap 4 drops IE9 support and goes full flexbox
For everyone saying &quot;Foundation&quot; when people ask what else... let me explain why Bootstrap is used so much more frequently than all other options combined.<p><a href="http:&#x2F;&#x2F;foundation.zurb.com" rel="nofollow">http:&#x2F;&#x2F;foundation.zurb.com</a>
vs
<a href="http:&#x2F;&#x2F;getbootstrap.com" rel="nofollow">http:&#x2F;&#x2F;getbootstrap.com</a><p>Each has a link to &#x27;download&#x27;.<p>Foundation&#x27;s link takes me to a page where I have a bunch of options, and a bit &quot;build a custom generated version&quot;.<p>Bootstrap&#x27;s takes me to a screen with 3 options, but also - and this is key - CDN links.  Right there.  I can paste a few lines in my HTML template and start working.<p>I don&#x27;t need to download&#x2F;generate code.<p>I don&#x27;t need to install node&#x2F;npm&#x2F;etc.<p>I don&#x27;t need to install and learn sass stuff.<p>I don&#x27;t need to make a lot of decisions or do a lot of extra unrelated stuff to get started.<p>Bootstrap is the PHP of the css&#x2F;grid&#x2F;framework world (for better and for worse).<p>I truly hope they keep the CDN hosted stuff for Bootstrap 4.<p>EDIT: didn&#x27;t mean to pick on foundation specifically - this &quot;take control of every aspect of all your layout&#x2F;grid&#x2F;css&quot; that most other frameworks require works to their disadvantage when it comes to popularity and uptake.
