Problema dimensiones

[xexuew]

Hola buenas tengo un problemilla.
El resto de mi web se me redimensiona dependiendo del tamaño de la pantalla pero el header y el menu no..
Alguna solución?

Código:

	header{
		
		width:100%;
		float:left;
		background: rgb(254,255,255); /* Old browsers */
		background: -moz-linear-gradient(top, rgba(254,255,255,1) 0%, rgba(225,223,223,1) 100%); /* FF3.6+ */
		background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(254,255,255,1)), color-stop(100%,rgba(225,223,223,1))); /* Chrome,Safari4+ */
		background: -webkit-linear-gradient(top, rgba(254,255,255,1) 0%,rgba(225,223,223,1) 100%); /* Chrome10+,Safari5.1+ */
		background: -o-linear-gradient(top, rgba(254,255,255,1) 0%,rgba(225,223,223,1) 100%); /* Opera 11.10+ */
		background: -ms-linear-gradient(top, rgba(254,255,255,1) 0%,rgba(225,223,223,1) 100%); /* IE10+ */
		background: linear-gradient(to bottom, rgba(254,255,255,1) 0%,rgba(225,223,223,1) 100%); /* W3C */
		filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#feffff', endColorstr='#e1dfdf',GradientType=0 ); /* IE6-9 */
	}

	header a{
