curly brace

基本解釋

One of the key features of Sass is its indentation-based syntax, which gives you curly-brace and semi-column free code.
Sass的一個(gè)關(guān)鍵特性是縮進(jìn)式的語法，這種語法可以產(chǎn)生柱式外觀的代碼。
There should be one space between the ) (right parenthesis) and the { (left curly brace) that begins the statement body.
(右括號)與開始程序體的{(左大括號)之間應(yīng)插入一個(gè)空格。
You'll want to remember to use the more explicit curly-brace form when your environment variable is not isolated from the surrounding text by whitespace (spaces or tabs).
請記住：當(dāng)環(huán)境變量沒有用空白（空格或制表鍵）與周圍文本分開時(shí)，請使用更明確的花括號形式。

So the open curly brace followed by the closed curly brace means everything inside of these curly braces should get executed, but only if that first condition is actually true.
所以左花括號后面跟著,右花括號，這意味著花括號里面所有的代碼,都應(yīng)該是要被執(zhí)行的，但只有當(dāng)?shù)谝粋€(gè)條件是正確的。

So when you define a function, you have, as we've seen these curly braces, that define all ; of the code that's associated with that function; open curly brace code, close curly brace, that is the function.
當(dāng)你定義一個(gè)函數(shù)，就像我們看到的這些花括號，定義了與,那個(gè)函數(shù)相關(guān)的所有代碼;,左花括號，代碼，右花括號，這就是一個(gè)函數(shù)。

They are correct, as the picture suggests, but then I hit that curly brace.
它們是正確的，就像那個(gè)圖所表示的，然后以那個(gè)花括號結(jié)束。
