Problemas de tamaño para plantilla wordpress

[Angel71]

Esto es lo que he visto en la parte de Apariencia/Editor de Wordpress

/* =Layout
-------------------------------------------------------------- */

#container {
float: none;
margin:0;
width: 100%;
margin-top:20px;
}
#content {
margin-bottom: 0px;
}
.sidey {
display:block;
float: left;
}

#footer {
clear: both;
width: 100%;
}

/* =Fonts
-------------------------------------------------------------- */


Y esto en la hoja de estilo de cada pagina a traves del codigo fuente pero no me deja modificar nada aqui :


</style>
<style type="text/css"> #header, #access, #colophon, #branding, #main, .topmenu { width: 1050px; } #header-full, #footer { min-width: 1050px; } #container.one-column { } #container.two-columns-right #secondary { width:330px; float:right; } #container.two-columns-right #content { width:700px; float:left; } #container.two-columns-left #primary { width:330px; float:left; } #container.two-columns-left #content { width:700px; float:right; } #container.three-columns-right .sidey { width:165px; float:left; } #container.three-columns-right #primary { margin-left:20px; margin-right:20px; } #container.three-columns-right #content { width:680px; float:left; } #container.three-columns-left .sidey { width:165px; float:left; } #container.three-columns-left #secondary { margin-left:20px;margin-right:20px; } #container.three-columns-left #content { width:680px; float:right;} #container.three-columns-sided .sidey { width:165px; float:left; } #container.three-columns-sided #secondary { float:right; } #container.three-columns-sided #content { width:680px; float:right; margin: 0 185px 0 -1050px; }
