 In a rule declaration, “selectors” are the bits that determine which elements in the DOM tree will be styled by the defined properties. Selectors can match HTML elements, as well as an element's class, ID, or any of its attributes. Here are some examples of selectors:

 * Prefer line comments (`//` in Sass-land) to block comments.
 * Prefer comments on their own line. Avoid end-of-line comments.
 * Write detailed comments for code that isn't self-documenting:
   - Uses of z-index
   - Compatibility or browser-specific hacks

-### ID selectors
+### Seletores ID
 
 While it is possible to select elements by ID in CSS, it should generally be considered an anti-pattern. ID selectors introduce an unnecessarily high level of [specificity](https://developer.mozilla.org/en-US/docs/Web/CSS/Specificity) to your rule declarations, and they are not reusable.

-### Variables
+### Variáveis
 
 Prefer dash-cased variable names (e.g. `$my-variable`) over camelCased or snake_cased variable names. It is acceptable to prefix variable names that are intended to be used only within the same file with an underscore (e.g. `$_my-variable`).
 
 ### Mixins
 
 Mixins should be used to DRY up your code, add clarity, or abstract complexity--in much the same way as well-named functions. Mixins that accept no arguments can be useful for this, but note that if you are not compressing your payload (e.g. gzip), this may contribute to unnecessary code duplication in the resulting styles.
 
-### Extend directive
+### Diretiva Extend
 
 `@extend` should be avoided because it has unintuitive and potentially dangerous behavior, especially when used with nested selectors. Even extending top-level placeholder selectors can cause problems if the order of selectors ends up changing later (e.g. if they are in other files and the order the files are loaded shifts). Gzipping should handle most of the savings you would have gained by using `@extend`, and you can DRY up your stylesheets nicely with mixins.
