Use css to directly define the input tag

<Style>
INPUT {
Color: expression (this. type = "button "? 'Red': 'Green ');
}
</Style>
<Input type = "button" name = "test" value = "haha">
<Input type = "text" name = "test2" value = "haha">
Css can be used to design the format. Sometimes, you can even directly define the html tag format. However, this tag is complicated for input. Type = select | type = button | type = text. Poor definition. So we can use the above method to define it.
If select is enabled
<Input type = "select" css = ". mystyle">
If it is <asp: button>
<Asp: button cssClass = ". mystyle">
In any case, you can set it to reduce traffic.
