jquery - Fixed and Variable Column Widths (Table or Float)? -

-

i'm creating 3 column, full width page want have 2 columns fixed width , other 1 fit full width between them, so:

| fixed width || variable width                || fixed width        | | left || adapts browser window size || fixed right |

i tried float didn't work , suggested using display-table worked until had edit page slightly. right hand column ok 2 left columns have content right down @ bottom , not @ top needs be. can please this. here code using:

    .pagecontent{         background-color: #dadee1;         width: 100%;         padding: 10px 0px 10px 0px;     }     .gridsystem{         display: table;     }     section{         display: table-cell;     }     .mainsidebar{         float: left;         vertical-align: top;         width: 140px;     }     .mainpage{         width: inherit;         overflow: hidden;         margin: 0px 0px 0px 0px;         padding: 20px;     }     .mainadvert{         float: right;         width: 140px;     }  <div class="pagecontent gridsystem">     <section class="mainsidebar"></section>     <section class="mainpage"></section>     <section class="mainadvert"></section>     <div class="clearboth"></div> </div>

try jquery solution:

$(document).ready(function(){     window_width = $(window).width;     mainpage_width = window_width - 140 - 140;      $(".mainpage").width = mainpage_width + "px";     }
