+Sass permite anidamiento (<code>nesting</code>) de reglas CSS, que es una forma útil de organizar una hoja de estilo. Normalmente, cada elemento se escribe en una línea diferente para darle estilo así:
 
 ```html
 nav {

-}

-nav ul { 
+nav ul {
   list-style: none;
 }
 
 nav ul li {
   display: inline-block;

 ```
 
-Para un proyecto grande, el archivo CSS tendrá muchas líneas y reglas. Aquí es donde el <code>nesting</code> puede ayudar a organizar su código al colocar reglas de estilo secundarias dentro de los respectivos elementos principales:
