It combines the robustness of Rust with SASS-like features such as nesting and variables for cleaner, more maintainable styles. 33 | 34 | ```rcss 35 | /* common/variables.rcss: 36 | let primary_color: "#FFFFFF"; 37 | let secondary_color: "black"; 38 | 39 | fn padding() { 40 | padding: 10px; 41 | } 42 | */ 43 | 44 | use common::variables::*; 45 | 46 | @import url('https://fonts.googleapis.com/css2?family=Roboto:ital,wght@0,100..900;1,100..900&family=Rubik:ital,wght@0,300..900;1,300..900&display=swap'); 47 | 48 | .container { 49 | width: 50%; 50 | padding(); 51 | 52 | &:hover { 53 | padding: 40px; 54 | } 55 | 56 | h2 { 57 | color: &primary_color; 58 | } 59 | } 60 | 61 | h4 { 62 | width: 50%; 63 | } 64 | 65 | 66 | /* MOBILE STYLES */ 67 | 68 | @media screen and (max-width: 480px) { 69 | .container { 70 | width: 100%; 71 | } 72 | 73 | h4 { 74 | width: 100%; 75 | color: &secondary_color; 76 | } 77 | } 78 | ``` 79 | 80 | > [!NOTE] 81 | > The above RCSS code compiles to CSS in around **500µs**! 82 | 83 | --- 84 | 85 |

    Usage

    144 |     145 |
146 |
147 | 148 | RCSS expects a directory argument to watch. On file save, RCSS will compile automatically to `../css` 149 | 150 | ```bash 151 | rcss-css styles/rcss 152 | ``` 153 | 154 | This command will compile `.rcss` files in `styles/rcss` into standard CSS files at `styles/css`. 155 | 156 | --- 157 | 158 |
