padding-top         =>      padding-top: 16px
padding-left        =>      padding-left: 16px

margin-horizontal   =>      margin: 0 16px
no-margin           =>      margin: 0

2. 自定义颜色

修改 ./src/theme/variables.scss 中

$colors: (
    primary:    #488aff,
    secondary:  #32db64,
    danger:     #f53d3d,
    light:      #f4f4f4,
    dark:       #222
);

可添加新颜色，如下：

twitter:( 
    base: #55acee, 
    contrast: #ffffff 
) 

base 作为元素背景色，contrast 作为文本颜色
在 html 中的使用如下：

<button ion-button color="twitter">I'm a button</button>

在 scss 中的使用如下：

my-component {
    background: color($colors, twitter, base);
}

3. 平台样式

第一列为Platform，第二列为Mode 
ios         =>      ios     
android     =>      md      
windows     =>      wp      
core        =>      md      

默认平台配置属性值：

覆写平台样式，如下：

.md .button {
    text-transform: capitalize;
}

或简写为：

}

4. 覆写Ionic Sass变量

详见Ionic Docs

5. RTL支持

$app-direction: multi // Both RTL and LTR
$app-direction: rtl // RTL only
$app-direction: ltr // LTR only

默认 LTR
详见Ionic Docs
