+If you are familiar with CSS or you have a stylesheet ready to paste, you may delete these comments and get started.
+CSS (Cascading Style Sheets) is a kind of code that tells the browser how to render a web page. Here's an example:
+img { border: 1px solid red; }
+That line basically means \"give images a red border one pixel thick.\"
+
+We hope you enjoy developing your custom CSS. Here are a few things to keep in mind:
+You can not edit the stylesheets of your theme. Your stylesheet will be loaded after the theme stylesheets, which means that your rules can take precedence and override the theme CSS rules.
+
+CSS comments will be stripped from your stylesheet. */
+
+/* This is a comment. Comments begin with /* and end with */
+
+/*
+Things we strip out include:
+ * HTML code
+ * @import rules
+ * expressions
+ * invalid and unsafe code
+ * URLs not using the http: protocol
+
+Things we encourage include:
+ * @media blocks!
+ * sharing your CSS!
+ * testing in several browsers!
