Introduction

In Part 7 of this article series we have seen that how to use single CSS file to a theme. Now in this article we have multiple CSS files as given below

Don't worry about the multiple CSS files because we have placed all files in the same directory named App_Themes/Simple. So, these all CSS files will be treated as single. I have used the name of all CSS files like SimpleStyle-A.css, SimpleStyle-B.css and SimpleStyle-C.css but you can use it as you wish. Using multiple CSS files has only one benefit that is all the css elements inside are separately and can be maintained very easily they has no any cross references. Here is the image of output as we have seen in previous part but after broking single css file in multiple has also the same result.

We have another option to use

    <link href="App_Themes/Simple/SimpleStyle-A.css" type="text/css" rel="stylesheet" />
    <link href="App_Themes/Simple/SimpleStyle-B.css" type="text/css" rel="stylesheet" />
    <link href="App_Themes/Simple/SimpleStyle-C.css" type="text/css" rel="stylesheet" />

above all are the another way to accomplish such task. If you are using above coding then there is no need of using Theme="Simple" at the top.

App_Themes\Simple\SimpleStyle-A.css File Code

{
    background-color:gray;
    font:14px Georgia,Serif;
}

.content
{
    margin:auto;
    width:600px;
    border:solid 1px black;
    background-color:White;
    padding:10px;
}

{
    color:Gray;
    font-size:18px;

}
