怎么让header干净整洁一点？

一直特别注重博客的外观，网站5月份就弄好了，一直在改，基本一天一个样。现在该到基本满意的样子了，但是header那一部分还不怎么满意，想把社交元素那块儿和搜索框那边去掉，我找到了这块的代码，能直接去掉吗？
/* Social-Search */#header .social-search {float: right;width: 306px;padding-right: 20px;margin-top: 40px;}ul.social-profile {list-style: none;margin: -10px 0 0;}#header ul.social-profile {float: right;}ul.social-profile li {float: left;margin: 10px 10px 0 0;}#header ul.social-profile li {margin: 10px 0 0 10px;}ul.social-profile li a {text-indent: -99999px;}ul.social-profile li a {background: url(images/social-profile.png) right bottom no-repeat; display: block;height: 33px; width: 33px;text-indent: -99999px;

上次我手贱想把底部的powered by链接去掉的，网站直接打不开，心里有阴影了。虽然出错还能改回来，但是太麻烦了，求给点建议
