+title: Built-in Microsite

+![](/img/radio-page.png)
+
+LibreTime includes a microsite, which can be accessed at _serverIP_ or a domain you've set up for your server. The site includes your
+logo and station description (set under Settings > General), the login button to the LibreTime interface, the schedule for the next seven days,
+podcast tabs, and a live feed of your station with information on the the currently playing artist and track.
+
+## Modifying the LibreTime Radio Page
+
+The background of the mini-site that appears when you visit the server's domain in your web browser can be changed by modifying the page's CSS file, located at `/usr/share/airtime/php/legacy/public/css/radio-page/radio-page.css`.
+
+```css
+html {
+  background: url("img/background-testing-3.jpg") no-repeat center center fixed;
+  -webkit-background-size: cover;
+  -moz-background-size: cover;
+  -o-background-size: cover;
+  background-size: cover;
+  overflow-y: auto;
+}
+```
+
+Place the new background image in the `/usr/share/airtime/php/legacy/public/css/radio-page/img/` folder and change the `background:` entry's URL to point to the new image. The new image should be at least 1280 x 720 in pixel size to avoid being blurry.
