CSS Style Syntax

Stylus transparently supports a regular CSS-style syntax. This means you don't need an alternative parser, or specify that a certain file uses a specific style.

Example

Below is a small style using the indented approach:

border-radius()  -webkit-border-radius arguments  -moz-border-radius arguments  border-radius arguments  body a  font 12px/1.4 "Lucida Grande", Arial, sans-serif  background black  color #ccc  form input  padding 5px  border 1px solid  border-radius 5px 
border-radius()  -webkit-border-radius arguments  -moz-border-radius arguments  border-radius arguments  body a  font 12px/1.4 "Lucida Grande", Arial, sans-serif  background black  color #ccc  form input  padding 5px  border 1px solid  border-radius 5px

Since braces, colons, and semi-colons are optional, we could write this example just as we would with normal CSS:

border-radius() {  -webkit-border-radius: arguments;  -moz-border-radius: arguments;  border-radius: arguments; }  body a {  font: 12px/1.4 "Lucida Grande", Arial, sans-serif;  background: black;  color: #ccc; }  form input {  padding: 5px;  border: 1px solid;  border-radius: 5px; } 
border-radius() {  -webkit-border-radius: arguments;  -moz-border-radius: arguments;  border-radius: arguments; }  body a {  font: 12px/1.4 "Lucida Grande", Arial, sans-serif;  background: black;  color: #ccc; }  form input {  padding: 5px;  border: 1px solid;  border-radius: 5px; }

While Stylus doesn't support every possible CSS-like syntax, it can understand even such code:

 border-radius() {  -webkit-border-radius: arguments;  -moz-border-radius: arguments;  border-radius: arguments;  }   body a  {  font: 12px/1.4 "Lucida Grande", Arial, sans-serif;  background: black;  color: #ccc;  }   form input {  padding: 5px;  border: 1px solid;  border-radius: 5px;  } 
 border-radius() {  -webkit-border-radius: arguments;  -moz-border-radius: arguments;  border-radius: arguments;  }   body a  {  font: 12px/1.4 "Lucida Grande", Arial, sans-serif;  background: black;  color: #ccc;  }   form input {  padding: 5px;  border: 1px solid;  border-radius: 5px;  }

Since we may mix and match the two variants, the following is valid as well:

border-radius()  -webkit-border-radius: arguments;  -moz-border-radius: arguments;  border-radius: arguments;  body a {  font: 12px/1.4 "Lucida Grande", Arial, sans-serif;  background: black;  color: #ccc; }  form input  padding: 5px;  border: 1px solid;  border-radius: 5px; 
border-radius()  -webkit-border-radius: arguments;  -moz-border-radius: arguments;  border-radius: arguments;  body a {  font: 12px/1.4 "Lucida Grande", Arial, sans-serif;  background: black;  color: #ccc; }  form input  padding: 5px;  border: 1px solid;  border-radius: 5px;

Variables, functions, mixins, and all the other features provided by Stylus still work as expected:

main-color = white main-hover-color = black  body a {  color: main-color;  &:hover { color: main-hover-color; } }  body a { color: main-color; &:hover { color: main-hover-color; }} 
main-color = white main-hover-color = black  body a {  color: main-color;  &:hover { color: main-hover-color; } }  body a { color: main-color; &:hover { color: main-hover-color; }}

There are a few caveats to this rule: since the two styles may be mixed and matched, some indentation rules still apply. So although not every plain-CSS stylesheet will work with zero modification, this feature allows those who prefer CSS syntax to continue doing so while leveraging Stylus' other powerful features.
