两个div 同行同高？？？？？？？？？？？？？

Question

我想让两个div在同一行并且高度相同希望大家多多帮忙！

我是这样做的

 <div  id="Holiday"  
            style=" margin-top:5px; margin-left:240px;height: 45px; width: 150px">
             <asp:Button ID="Button1" runat="server" Text="Button" /></div>
       <div  id="Div2"  
            style=" margin-top:-25px; margin-left:150px;height: 45px; width: 164px">
           <asp:Button ID="Button2" runat="server" Text="Button" />
       </div>

用的相对位置但是运行后Button1不能点击要是里面是textbox不能写文字其他控件也不行！
