Bootstrap 2 or Bootstrap 3 for IE 7 Performance Wise -
while know not vs b topics hear me out.
bootstrap 3 has been released countless improvements. 1 potential deal breaker drops ie 7 compatibility. site's cater corporate users unfortunately isn't practical since in 1 particular use case 10% market still.
so supporting ie7 must 1 think means choosing stick bootstrap 2. however, https://github.com/coliff/bootstrap-ie7 1 can add ie7 support while keeping benefits of bootstrap 3.
the 1 issue must use boxsizing.htc polyfill ie 7 users (https://github.com/schepp/box-sizing-polyfill)
so question better stick bootstrap 2 or switch bootstrap 3.0 boxsizing.htc? b3 .htc slower 10% ie7 users b2, if barely noticeable (especially if server caching) worth benefits rest of 90%.
if know 1 knows, next thing guess test installing default b2 , b3 .htc demo sites , comparing speeds in ie7.
ps if there better polyfill adding boxsizing ie7 1 listed above performance wise let me know.
i faced similar dilemma bootstrap 3/ie7, landed on different solution. zout, couldn't patch work, wrote 1 doesn't require polyfill.
it works falling bootstrap 2 type grid system of fluid columns no padding , left margin beginning second column. in ie7 bootstrap 3, site looks perfect.
i've tested (and works) of components of bootstrap. includes fixes ie layout bugs , other odd behaviors.
i put on github yesterday. hope helps:
