html - Does a row within a container require span12? Bootstrap -


i using bootstrap first time work on project of mine. , can tell container>row works fine, begs questions container>row>span12 needed, or best practice?

thank you

the question confusing.

bootstrap works using floated grid system. looking @ source below should clear going on. .container class sets width of 940px, .span12 class. .row class div clearfix on contain row of floated .span columns. .spanxx classes floated left , given 20px left margin create grid.

if using container , row, creating 940px wide container -20px left-margin. should still use .span12 keep consistent framework , set margin correctly. raises question, why using grid layout in first place if don't want take advantage of columns. if want 940px container create one.

from bootstrap.css:

.row {   margin-left: -20px;   *zoom: 1; }  .row:before, .row:after {   display: table;   line-height: 0;   content: ""; }  .row:after {   clear: both; }  [class*="span"] {   float: left;   margin-left: 20px; }  .container, .navbar-static-top .container, .navbar-fixed-top .container, .navbar-fixed-bottom .container {   width: 940px; }  .span12 {   width: 940px; }
