# Custom theme Streams Manager offers the ability to fully customize your theme as part of the premium feature pack. This allows you to create a fully custom theme with custom color and layout but you need to be familiar with CSS. ## Creating your custom theme It may be easiest to start with an existing Bootstrap 4 theme (system is build on Bootstrap 4 so maximum version of Bootstrap that is supported is 4) and modify from there, but that is completely up to you. You can find Bootstrap 4 themes at: and many other places on the Internet. We also have a dark theme with blue nav bar that you can use as a starting point that is based on Darkly bootswatch theme: and you can get it [here](https://api.streamsmanager.com/css/darkly.css). Alternatively, you can try create a completely custom theme with the help of [https://www.bootstrap-live-customizer.com](https://www.bootstrap-live-customizer.com/). Modify the theme as you see fit and save the file somewhere on your computer ## Testing your custom theme Follow these steps to see how your custom CSS theme looks before uploading it. Steps below work for Chrome browsers but other browsers work similarly. * Store your custom CSS file in a folder that is accessible by your user * Open your Stream Manager site in a browser * Open developer tools * Right click anywhere on the page and select Inspect * Click on the Elements tab * Expand head element and find client theme link element * ```
``` * Replace the `href=` portion with `file:///full-path-to-css-file` using the full path to your CSS file (i.e. `file:///C:/Users/Admin/Downloads/my.css`) * Press enter and your changes should be reflected ## Upload your custom theme {% hint style="warning" %} Please note that because CDN caches the file, it may take 6 hrs for changes to take effect. {% endhint %} To see how the theme looks, upload the CSS file in `Settings -> Custom Content -> Custom CSS` section and fully reload the page. You can also reset the theme to default if something is not looking right. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
