Wordpress：导航菜单中的按钮

Question

请您帮我在导航菜单中设置文字样式吗？我希望它看起来像一个按钮。

它有这段代码：

<li id="main-menu-item-2217" class="free_download btn btn-mini btn-primary menu-item menu-item-type-post_type menu-item-object-page">

.navbar .nav li.free_download.btn {
position: relative;
bottom: 10px;
padding: 2px;
line-height: 19px;
vertical-align: middle;
}

.navbar .nav li.free_download.btn a {
color: #FFF;
text-shadow: 0 -1px 0 rgba(0, 0, 0, 0.31);
padding: 3px 13px;
}

it looks like this now..

I want it to look like this.

谢谢。
