在主题中添加CSS

如果在主题文件夹中添加CSS文件,则在页面应用主题时也会自动应用CSS。

SimpleStyle\SimpleSheet.css
html {
  background-color:Gray;
  font:14px Georgia,Serif;
}
.content
{
    margin:auto;
    width:600px;
    border:solid 1px black;
     background-color:White;
     padding:10px;
    }
h1
{
     color:Gray;
     font-size:18px;
     border-bottom:solid 1px orange;
}
    
label
{
  font-weight:bold;
}
input
 {          
    background-color:Yellow;

注意:
   使用CSS的好处是使加载页面的速度更快。
   尽量不要通过修改控件属性来对控件进行格式化。使用<style>

1、在主题中添加多个CSS
<link href="App_Themes/StyleTheme/SimpleSheet.css" type="text/css" rel="stylesheet" />
<link href="App_Themes/StyleTheme/SimpleSheet2.css" type="text/css" rel="stylesheet" />
<link href="App_Themes/StyleTheme/SimpleSheet3.css" type="text/css" rel="stylesheet" />

2、使用CSS改变页面布局
使用CSS可以改变页面布局,所以使用主题可以控制页面布局

Float.css 放在主题中

html
{
background-color:Silver;
font:14px Arail,Sans-Serif;
}

#div1
{
float:left;
width:25%;
margin:15px;
padding:10px;
background-color:White;   
}

#div2
{
float:left;
width:25%;
margin:15px;
padding:10px;
background-color:White;   
}

#div3
{
float:left;
width:25%;
margin:15px;
padding:10px;
background-color:White;   
}
