css – SUSY2 – 教學範例 – mixin、function 介紹

2014-09-19 / JSN / 3 Comments / 817 views

這篇主要是方便以後編撰SUSY的時候可以查閱。介紹我在開發中常用的mixin與function，很少用到的方法就不在此列出囉！以下介紹內容可以配合官方網站，以寬螢幕 12 柵欄為Demo，至於 RWD的佈局，則參考前兩篇：基本、進階佈局

有即時預覽可以參考，但是只有一支SCSS檔，比較凌亂。

Play with this gist on SassMeister.

基本上建議在本機練習實作時，分割兩支檔案。

_base.scss 基本設定檔

@import "compass/css3";

@import "susy";

@import "breakpoint";

$susy: (

flow: ltr,

math: fluid,

output: float,

gutter-position: after,

container: auto,

container-position: center,

columns: 4,

gutters: 1/4,

column-width: 60px,

global-box-sizing: content-box,

last-flow: to,

debug: (

image: show,

color: rgba(#66f, .25),

output: background,

toggle: top right,

use-custom: (

background-options: false,

box-sizing: true,

clearfix: false,

rem: true,

)

);

//設定三種尺寸

$break_layout :

(

mobile:

(

break: 0px,

pad:

(

break: 640px,

desktop:

(

break: 1280px,

)

);

//方便撰寫的自訂 mixin 斷點樣式

@mixin _break($screen: mobile)

{

$map : map-get($break_layout, $screen);

$break: map-get($map, "break");

$layout: map-get($map, "layout");

@include susy-breakpoint($break, $layout)

{

@content;

}

//隨機背景色

@mixin rand_bg()

{

background: rgba(random(255), random(255), random(255), 0.7);

}

<body>

<h3>@include span($span) <br>佔柵欄數</h3>

<div class="span2">span2 span2 span2 span2 span2(當前方有float，我若不clear:both，基本上會有重疊)</div>

<h3>@include span(2 wide) <br>外部擴展單側gutter寬度</h3>

<div class="span3">使用了 wide 使用了擴展一側的gutter</div>

<h3>@include span(2 wider) <br>外部擴展兩側gutter寬度</h3>

<div class="span4">使用了 wider 擴展兩側 gutter</div>

<h3> @include full <br> 全部柵欄。一種 span(full) 的簡寫。</h3>

<div class="full">不論你的layout()多少，都橫跨所有柵欄</div>

<h3>gutter() <br>裡面不帶任何數字，<br>該function會使用當前的gutter寬度(柵欄之間的溝寬), <br>如果當前12柵欄，就返回12柵欄的1個gutter寬度</h3>

<div class="gutter">gutter</div>

<h3>@include gutter(); 或 @include gutter($span); <br> 依照map預設的 gutter-position: after, 若明確指定數字，就是返回指定layout的gutter寬度。<br>如 @include gutter(12); 代表返回12柵欄的1個gutter寬度</h3>

<div class="gutter2">@include gutter(); 12柵欄下的1gutter寬度</div>

<div class="gutter3">@include gutter(4); 硬是要在12柵欄下，使用4柵欄的1gutter寬度。通常這種方式會造成混亂，盡量不使用。</div>

<h3>@include break; <br> 可強制換行, 其實就是使用清除的CSS => clear:both</h3>

<div class="break_span">break_span(我右邊還有空間)</div>

<div class="break_span2">break_span2 break_span2 break_span2 break_span2 break_span2 (若有空間我會跑上來)</div>

<div class="break_break">break_break(不管，我就是要新的一行)</div>

<h3>@include last; <br> 指定為最後的元素。<br>如同susy one 的 omega，可以當mixin也可以是寫在span() 裡的keyword <br> 另有 @include first，但須另做設定，詳見官網</h3>

<div class="last_span2">last_span2(我是最後一個)</div>

<h1>Margin 系列</h1>

<h3>@include pre(3 of 12); <br> 像是 margin-left 的功能 </h3>

<div class="pre">margin_pre margin_pre margin_pre margin_pre margin_pre margin_pre </div>

<h3>@include post(4 of 12); <br> 像是 margin-right 的功能 </h3>

<div class="post">margin_post margin_post margin_post margin_post margin_post margin_post (檢視元素可以發現右側有佔柵欄)</div>

<h3>@include pull(2 of 12); <br> 往前拉的意思，所以有 2 + 12 行柵欄 </h3>

<div class="pull">margin_pull margin_pull margin_pull margin_pull margin_pull margin_pull margin_pull margin_pull margin_pull margin_pull margin_pull margin_pull margin_pull margin_pull margin_pull margin_pull margin_pull margin_pull </div>

<h3>@include squish(2, 3); <br> 兩側擠壓的意思，也就是同時使用 pre() 與 post() </h3>

<div class="squish">margin_squish margin_squish margin_squish margin_squish margin_squish margin_squish margin_squish margin_squish margin_squish margin_squish margin_squish margin_squish margin_squish margin_squish margin_squish </div>

<h1>Padding 系列</h1>

<h3>@include prefix(1 of 12); <br> 像是 padding-left 的功能 </h3>

<div class="prefix">padding_prefix padding_prefix padding_prefix padding_prefix padding_prefix padding_prefix padding_prefix padding_prefix padding_prefix padding_prefix padding_prefix padding_prefix padding_prefix padding_prefix </div>

<h3>@include suffix(3 of 12); <br> 像是 padding-right 的功能 </h3>

<div class="pad">padding_pad padding_pad padding_pad padding_pad padding_pad padding_pad padding_pad padding_pad padding_pad padding_pad padding_pad padding_pad padding_pad padding_pad padding_pad padding_pad padding_pad padding_pad </div>

<h3>@include bleed(20px 10px 0px 50px); <br> 流血。像是傷口的血液往外擴散，超出傷口範圍。依序指定上右下左的超出範圍 </h3>

<div class="bleed">padding_bleed padding_bleed padding_bleed padding_bleed padding_bleed padding_bleed padding_bleed padding_bleed padding_bleed padding_bleed padding_bleed padding_bleed padding_bleed padding_bleed padding_bleed </div>

<h3>@include bleed-x(1em); <br> 水平的流血範圍。</h3>

<div class="bleed_x">padding_bleed_x padding_bleed_x padding_bleed_x padding_bleed_x padding_bleed_x padding_bleed_x </div>

<h3>@include bleed-y(1em); <br> 垂直的流血範圍。</h3>

<div class="bleed_y">padding_bleed_y padding_bleed_y padding_bleed_y padding_bleed_y padding_bleed_y </div>

<h3>margin-left: isolate(2 of 12);<br> 用在function會返回一個數值。距離左邊 12柵欄中第2欄位開始的位置。</h3>

<div class="isolate_function">isolate_function isolate_function isolate_function isolate_function isolate_function </div>

<div class="isolate_function2">isolate_function2 isolate_function2 isolate_function2 </div>

<h3>@include isolate(50%);<br> 從一個指定的位置中獨立出來。因為是獨立的，所以會重疊喔。</h3>

<div class="isolate_mixin">isolate_mixin isolate_mixin isolate_mixin isolate_mixin isolate_mixin isolate_mixin isolate_mixin isolate_mixin isolate_mixin isolate_mixin isolate_mixin isolate_mixin isolate_mixin isolate_mixin </div>

<div class="isolate_mixin2">isolate_mixin2 isolate_mixin2 isolate_mixin2 isolate_mixin2 </div>

<h3>@include span(isolate 2 at 7); <br> 從第7個柵欄開始，佔2柵欄。因為是獨立的，所以會重疊喔。</h3>

<div class="isolate_keyword">isolate_keyword isolate_keyword isolate_keyword isolate_keyword isolate_keyword </div>

<div class="isolate_keyword2">isolate_keyword2 isolate_keyword2 isolate_keyword2 isolate_keyword2 isolate_keyword2 isolate_keyword2 isolate_keyword2 isolate_keyword2 isolate_keyword2 isolate_keyword2 </div>

<h3>@include gallery(4 of 12);<br> 最重要的！<br>固定寬度時需要程式做 loop ，就是使用它。<br> 無須理會最右側或最左側是否添加 first 或 last 。<br> 如同 susy one 的 susy one isolate-grid() <br><br> 因為是使用 CSS 的 :nth-child 原理，<br>所以要 loop的元素最外層，務必添加一層元素做包圍。</h3>

<div class="gallery">gallery</div>

不同顯示裝置同樣有一個問題，就是我們希望在不同顯示裝置套用不同的動態效果，那要如何偵測當前是手機、平板、還是桌電呢，就請參考這篇。
