[求助]一个鼠标经过的效果

有文字“首页”当鼠标经过的时候，变成粗体“首页”，离开的时候，变回原样。
请问怎么弄？

你可以用css做; 还有我告诉你;如查你看中你喜欢的有类似的网站风格你可以用一个网站离线下载器把他的网站的下载下来;

这个我会,够大吧,哈哈

<style>
<!--
.bolderClass {
    font-weight:900;
    font-size: 400px;
}
-->
</style>
<div onmouseover=\"this.className='bolderClass'\" onmouseout=\"this.className='';\">首页</div>

lmhllr  你的技术我是信得过的，但是，~我要变粗体，不是变这么大的字体~~~

粗体应该也有那个属性吧

3楼的老大你也太夸张了撒
楼主可以在3楼的代码内修改下撒

<style>
<!--
.font_B {
    font-weight:900;
    //font-size: 18px;
}
-->
</style>
<div onmouseover=\"this.className='font_B'\" onmouseout=\"this.className='';\">加粗</div>
