Ionic Css样式详解

Header是固定在屏幕顶部的组件。可以包含如标题和左右的功能按钮。Sub Header同样是固定在顶部，只是是在Header的下面，就算没有写Header这个，Sub Header这个样式也会距离顶部有一个Header的距离。

如：

1

<ion-view> <ion-content class="no-header"> <div class="bar bar-header bar-royal"> <a href="#/app/capture" class="button button-icon icon ion-gear-a"></a> <h1 class="title">Header</h1> <a href="#/app/playlists" class="button button-icon icon ion-heart"></a> </div> <div class="bar bar-subheader"> <h2 class="title">Sub Header</h2> <a href="#/app/playlists" class="button button-icon icon ion-ios7-undo-outline"></a> <a href="#/app/capture" class="button button-icon icon ion-ios7-redo-outline"></a> </div> </ion-content> </ion-view>

仔细的读者可能发现，我在header和subheader里面各自放了两个按钮，我并没有定位，ionic会自动将两个分开在两边。经测试，ionic会自动把header或subheader里面的最后一个图标靠右，其他的靠左依次摆开。

Footer

footer是显示在屏幕底部的边栏，你可以用这个做导航栏或者添加一些菜单操作，示例如下：

1	<div class="bar bar-footer bar-balanced"> <button class="button button-clear">Left</button> <div class="title"> <button ng-click="captureVideo();" class="button button-clear button-icon icon ion-ios7-videocam-outline"></button></div> <button class="button button-clear">Right</button> </div>

值得注意的是，在bar-footer和bar-header里面一样，class=title的元素都会被自动居中。如果没有的话，会自动向左排列。可以使用如下pull-right方式让其靠右排列：（header里面也一样）

1	<div class="bar bar-footer"> <button class="button button-clear pull-right">Right</button> </div>

button

1. button的默认情况是按照display: inline-block来显示，宽度是随其内部文字长度增长的。
   有许多不同的显示样式。

   1

   <button class="button"> Default </button> <button class="button button-light"> button-light </button> <button class="button button-stable"> button-stable </button> <button class="button button-positive"> button-positive </button> <button class="button button-calm"> button-calm </button> <button class="button button-balanced"> button-balanced </button> <button class="button button-energized"> button-energized </button> <button class="button button-assertive"> button-assertive </button> <button class="button button-royal"> button-royal </button> <button class="button button-dark"> button-dark </button>

1. 如果想让button占满父元素宽度，父元素没有padding的话，就是屏幕宽度，需要加上 button-block 样式

   1	<button class="button button-full button-positive"> Full Width Block Button </button>

1. 当然还有可以控制button大小的默认样式，button-small，button-large

   1	<button class="button button-small button-assertive"> Small Button </button> <button class="button button-large button-positive"> Large Button </button>

1. 还有只显示框线的button，样式button-outline

   1	<button class="button button-outline button-positive"> Outlined Button </button>

1. 还有不显示框的button，样式button-clear

   1	<button class="button button-clear button-positive"> Clear Button </button>

1. 带icon的button，可以控制icon的位置，直接看代码

   1

   <button class="button"> <i class="icon ion-loading-c"></i> Loading... </button> <button class="button icon-left ion-home">Home</button> <button class="button icon-left ion-star button-positive">Favorites</button> <a class="button icon-right ion-chevron-right button-calm">Learn More</a> <a class="button icon-left ion-chevron-left button-clear button-dark">Back</a> <button class="button icon ion-gear-a"></button> <a class="button button-icon icon ion-settings"></a> <a class="button button-outline icon-right ion-navicon button-balanced">Reorder</a>

1. 放在header的button，注意button-icon样式和button-clear样式

   1

   <div class="bar bar-header"> <button class="button icon ion-navicon"></button> <h1 class="title">Header Buttons</h1> <button class="button">Edit</button> </div> <div class="bar bar-header"> <button class="button button-icon icon ion-navicon"></button> <div class="h1 title">Header Buttons</div> <button class="button button-clear button-positive">Edit</button> </div>

1. 一组button，注意button-bar样式，可以与其他的icon组合

   1	<div class="button-bar"> <a class="button">First</a> <a class="button">Second</a> <a class="button">Third</a> </div>

List

1. list列表是一个比较常用的组件，list views支持很多的交互操作，比如编辑，划屏幕编辑，拖拽排序，下拉刷新等等。可以参看javascript API中的list介绍，这里给个综合的例子：

   1

   <ion-list ng-controller="MyCtrl" show-delete="shouldShowDelete" show-reorder="shouldShowReorder" can-swipe="listCanSwipe"> <ion-item ng-repeat="item in items" class="item-thumbnail-left"> <img ng-src="{{item.img}}"> <h2>{{item.title}}</h2> <p>{{item.description}}</p> <ion-option-button class="button-positive" ng-click="share(item)"> Share </ion-option-button> <ion-option-button class="button-info" ng-click="edit(item)"> Edit </ion-option-button> <ion-delete-button class="ion-minus-circled" ng-click="items.splice($index, 1)"> </ion-delete-button> <ion-reorder-button class="ion-navicon" on-reorder="reorderItem(item, $fromIndex, $toIndex)"> </ion-reorder-button> </ion-item> </ion-list>

上图中那个有一行是向左划屏出现的效果。

1. list分栏，主意item-divider样式

   1	<div class="list"> <div class="item item-divider"> Candy Bars </div> <a class="item" href="#"> Butterfinger </a> ... </div>

1. 带有icon的list，可以通过i标签添加icon到item中，通过item-icon-left或item-icon-right指定icon在左边还是右边。下面的例子中使用a或button标签做每个item，主要是为了让这每个item可以tappable，还有一个特点是当没有添加任何icon时，会自动在右边添加一个小的向右的箭头图标。直接看例子：

   1

   <div class="list"> <a class="item item-icon-left" href="#"> <i class="icon ion-email"></i> Check mail </a> <a class="item item-icon-left item-icon-right" href="#"> <i class="icon ion-chatbubble-working"></i> Call Ma <i class="icon ion-ios7-telephone-outline"></i> </a> <a class="item item-icon-left" href="#"> <i class="icon ion-mic-a"></i> Record album <span class="item-note"> Grammy </span> </a> <a class="item item-icon-left" href="#"> <i class="icon ion-person-stalker"></i> Friends <span class="badge badge-assertive">0</span> </a> </div>

1. 带有button的list，注意item-button-right or item-button-left样式

   1	<div class="list"> <div class="item item-button-right"> Call Ma <button class="button button-positive"> <i class="icon ion-ios7-telephone"></i> </button> </div> ... </div>

1. 带有头像的item，主意item-avatar样式

   1	<div class="list"> <a class="item item-avatar" href="#"> <img src="venkman.jpg"> <h2>Venkman</h2> <p>Back off, man. I'm a scientist.</p> </a> ... </div>

1. 带有缩略图的list，注意item-thumbnail-left 和 item-thumbnail-right样式，可以指定缩略图不同的显示位置。

   1	<div class="list"> <a class="item item-thumbnail-left" href="#"> <img src="cover.jpg"> <h2>Pretty Hate Machine</h2> <p>Nine Inch Nails</p> </a> ... </div>

1. 表格样式的list，这个主要是有了margin的样式，显示两边的框线。注意样式list list-inset。可以参考后面的inset-forms效果。

   1	<div class="list list-inset"> <div class="item"> Raiders of the Lost Ark </div> ... </div>

卡片card

1. card卡片一起整洁内容涵盖丰富的表现形式，在应用中使用的越来越多。card默认样式带有box-shadow，由于性能的原因，和他类似的元素像list list-inset 并没有shadow。如果你有很多的card，每个card都有很多子元素，建议使用inset list。下面是一个简单的带有footer和header的card。

   1	<div class="card"> <div class="item item-divider"> I'm a Header in a Card! </div> <div class="item item-text-wrap"> This is a basic Card with some text. </div> <div class="item item-divider"> I'm a Footer in a Card! </div> </div>

1. 列表形式的card，主意list card 样式

   1

   <div class="list card"> <a href="#" class="item item-icon-left"> <i class="icon ion-home"></i> Enter home address </a> <a href="#" class="item item-icon-left"> <i class="icon ion-ios7-telephone"></i> Enter phone number </a> <a href="#" class="item item-icon-left"> <i class="icon ion-wifi"></i> Enter wireless password </a> <a href="#" class="item item-icon-left"> <i class="icon ion-card"></i> Enter card information </a> </div>

1. 带有图像的组合显示的card

   1

   <div class="list card"> <div class="item item-avatar"> <img src="avatar.jpg"> <h2>Pretty Hate Machine</h2> <p>Nine Inch Nails</p> </div> <div class="item item-image"> <img src="cover.jpg"> </div> <a class="item item-icon-left assertive" href="#"> <i class="icon ion-music-note"></i> Start listening </a> </div>

1. card显示风格的示例。该实例综合多种元素，主意item-avatar，item-body，item-divider等样式

   1

   <div class="list card"> <div class="item item-avatar"> <img src="mcfly.jpg"> <h2>Marty McFly</h2> <p>November 05, 1955</p> </div> <div class="item item-body"> <img class="full-image" src="delorean.jpg"> <p> This is a "Facebook" styled Card. The header is created from a Thumbnail List item, the content is from a card-body consisting of an image and paragraph text. The footer consists of tabs, icons aligned left, within the card-footer. </p> <p> <a href="#" class="subdued">1 Like</a> <a href="#" class="subdued">5 Comments</a> </p> </div> <div class="item tabs tabs-secondary tabs-icon-left"> <a class="tab-item" href="#"> <i class="icon ion-thumbsup"></i> Like </a> <a class="tab-item" href="#"> <i class="icon ion-chatbox"></i> Comment </a> <a class="tab-item" href="#"> <i class="icon ion-share"></i> Share </a> </div> </div>

表单输入

关于html5支持的输入类型，参考我的另外一篇HTML5输入类型

1. 基本的表单，主意textarea标签，其他的主意placeholder属性

   1	<div class="list"> <label class="item item-input"> <input type="text" placeholder="First Name"> </label> <label class="item item-input"> <input type="text" placeholder="Last Name"> </label> <label class="item item-input"> <textarea placeholder="Comments"></textarea> </label> </div>

1. 带有标签的输入框,注意input-label样式

   1	<div class="list"> <label class="item item-input"> <span class="input-label">Username</span> <input type="text"> </label> <label class="item item-input"> <span class="input-label">Password</span> <input type="password"> </label> </div>

1. 堆栈式的表单，注意item-stacked-label样式

   1

   <div class="list"> <label class="item item-input item-stacked-label"> <span class="input-label">First Name</span> <input type="text" placeholder="John"> </label> <label class="item item-input item-stacked-label"> <span class="input-label">Last Name</span> <input type="text" placeholder="Suhr"> </label> <label class="item item-input item-stacked-label"> <span class="input-label">Email</span> <input type="text" placeholder="john@suhr.com"> </label> </div>

1. 动态显示标签的堆栈式表单，注意item-floating-label样式，而且这个是和input-label样式的元素对应的，两者搭配使用。

   1

   <div class="list"> <label class="item item-input item-floating-label"> <span class="input-label">First Name</span> <input type="text" placeholder="First Name"> </label> <label class="item item-input item-floating-label"> <span class="input-label">Last Name</span> <input type="text" placeholder="Last Name"> </label> <label class="item item-input item-floating-label"> <span class="input-label">Email</span> <input type="text" placeholder="Email"> </label> </div>

1. 默认的form是满屏宽度的，还有一种 inset form 是带有padding的，类似inset list的样式。

   1	<div class="list list-inset"> <label class="item item-input"> <input type="text" placeholder="First Name"> </label> <label class="item item-input"> <input type="text" placeholder="Last Name"> </label> </div>

1. 内嵌输入样式，和form一样，这种输入框并不是100%宽的。注意item-input-inset样式。

   1	<div class="list"> <div class="item item-input-inset"> <label class="item-input-wrapper"> <input type="text" placeholder="Email"> </label> <button class="button button-small"> Submit </button> </div> </div>

1. 带有icon的输入框，可以很轻松的给item-input元素添加icon，也可以添加placeholder内容

   1	<div class="list list-inset"> <label class="item item-input"> <i class="icon ion-search placeholder-icon"></i> <input type="text" placeholder="Search"> </label> </div>

1. header上的输入框

   1	<div class="bar bar-header item-input-inset"> <label class="item-input-wrapper"> <i class="icon ion-ios7-search placeholder-icon"></i> <input type="search" placeholder="Search"> </label> <button class="button button-clear"> Cancel </button> </div>

Toggle选择

toggle是一种比较容易操作的多选框，类似于checkbox，只不过表现上更容易操作，这里是用label标签包裹toggle组件，为了是更容易操作。

1	<ul class="list"> <li class="item item-toggle"> HTML5 <label class="toggle toggle-assertive"> <input type="checkbox"> <div class="track"> <div class="handle"></div> </div> </label> </li> ... </ul>

checkbox多选框

多选框是一种常见的html组件，这里同样使用label包裹多选框，为了方便实现tap操作，label标签中可以使用checkbox-assertive来指定选中激活时的颜色。

1	<ul class="list"> <li class="item item-checkbox"> <label class="checkbox"> <input type="checkbox"> </label> Flux Capacitor </li> ... </ul>

radio单选框

通过item-radio来表示单选框，每个都有相同的name属性，radio-icon样式的标签用来指定显示勾选的icon。这里同样使用label包裹整个组件，为了方便操作

1	<div class="list"> <label class="item item-radio"> <input type="radio" name="group"> <div class="item-content"> Go </div> <i class="radio-icon ion-checkmark"></i> </label> ... </div>

range范围选择

range组件用于在某个范围内选择值。

1

<div class="range"> <i class="icon ion-volume-low"></i> <input type="range" name="volume"> <i class="icon ion-volume-high"></i> </div> <div class="list"> <div class="item range range-positive"> <i class="icon ion-ios7-sunny-outline"></i> <input type="range" name="volume" min="0" max="100" value="33"> <i class="icon ion-ios7-sunny"></i> </div> </div>

select下拉选框

下拉框用于在多个候选项中选择一个值，不同的浏览器表现形式不一样。注意item-select样式。

1	<div class="list"> <label class="item item-input item-select"> <div class="input-label"> Lightsaber </div> <select> <option>Blue</option> <option selected>Green</option> <option>Red</option> </select> </label> </div>

tabs组件

1. tabs是水平排列的button或link，用于切换视图。是一种很常用的导航方法。

   1	<div class="tabs"> <a class="tab-item"> Home </a> <a class="tab-item"> Favorites </a> <a class="tab-item"> Settings </a> </div>

1. 仅有图标的tabs

   1	<div class="tabs tabs-icon-only"> <a class="tab-item"> <i class="icon ion-home"></i> </a> <a class="tab-item"> <i class="icon ion-star"></i> </a> <a class="tab-item"> <i class="icon ion-gear-a"></i> </a> </div>

1. icon在上，下有文字的tabs，注意tabs-icon-top样式
