Code Examples in Markdown

Syntax highlighting with GFM

+ 
+```javascript
+function fancyAlert(arg) {
+  if(arg) {
+    $.facebox({div:'#foo'})
+  }
+}
+```
+
+
+

Or, indent your code 4 spaces

+ 
+Here is a Python code example
+without syntax highlighting:
+
+    def foo:
+      if not bar:
+        return true

Code Examples in Markdown

-
-

Syntax highlighting with GFM

- 
-```javascript
-function fancyAlert(arg) {
-  if(arg) {
-    $.facebox({div:'#foo'})
-  }
-}
-```
-
-
-

Or, indent your code 4 spaces

- 
-Here is a Python code example
-without syntax highlighting:
-
-    def foo:
-      if not bar:
-        return true
-
-
-

Inline code for comments

- 
-I think you should use an
-`<addr>` element here instead.
