# Adding CSS and JS files AppThemes often require their own CSS and JavaScript files.  This can be done inline in the template or by linking to a file. #### Adding a CSS file Create a folder.. ```plaintext /DesktopModules/RocketThemes/AppThemes-W3-CSS/rocketcontentapi.example1/1.0/css ``` Create a CSS file called "example1.css" in this folder and add any CSS required. The CSS file is added to the AppTheme by using the dependency file. Create a folder called "dep" in the AppTheme ```plaintext /DesktopModules/RocketThemes/AppThemes-W3-CSS/rocketcontentapi.example1/1.0/dep ``` Create a file called "example1.dep" with the following XML format.  This example is using the {appthemefolder} token. ```plaintext <genxml> <deps list="true"> <genxml> <ctrltype>css></ctrltype> <url>{appthemefolder}/css/example1.css></url> <ecofriendly>true</ecofriendly> </genxml> </deps> </genxml> ``` This ensures that the resource "example1.css" is not loaded onto the page multiple times if multiple AppThemes require it. #### Adding a JS file Create a folder.. ```plaintext /DesktopModules/RocketThemes/AppThemes-W3-CSS/rocketcontentapi.example1/1.0/js ``` Create a JS file called "example1.js" in this folder and add any JS required. The JS file is added to the AppTheme by using the dependency file. Create a folder called "dep" in the AppTheme ```plaintext /DesktopModules/RocketThemes/AppThemes-W3-CSS/rocketcontentapi.example1/1.0/dep ``` Create a file called "example1.dep" with the following XML format.  This example is using the {appthemefolder} token. ```plaintext <genxml> <deps list="true"> <genxml> <ctrltype>css></ctrltype> <url>{appthemefolder}/css/example1.js></url> <ecofriendly>true</ecofriendly> </genxml> </deps> </genxml> ``` This ensures that the resource "example1.js" is not loaded onto the page multiple times if multiple AppThemes require it.
