Hello and good wishes for Easter.I have a problem with the 'use of Bootstrap.The code is as follows:\[code\]<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Landing Page</title> <!-- Bootstrap --> <link href="http://stackoverflow.com/questions/15728336/bootstrap/css/bootstrap.min.css" rel="stylesheet" media="screen"> <link href="http://stackoverflow.com/questions/15728336/bootstrap/css/bootstrap-responsive.css" rel="stylesheet"> <link href="http://stackoverflow.com/questions/15728336/bootstrap/css/custom.css" rel="stylesheet" media="screen"> <!-- Javascript --> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"></script> <script src="http://stackoverflow.com/questions/15728336/bootstrap/js/bootstrap.min.js"></script> </head> <body> <div class="container"> <div class="row" id="main_header"> </div> </div> </body></html>\[/code\]But the result is that the row is larger than the container.I leave you a picture to understand what I mean(In custom.css there are only the height and the colors of the div )I hope you can help me, thanks in advance
