定位

用于定位内容的实用class的集合。

用法

应用此组件，请在块元素内添加一个.uk-position-* class。使用此组件将内容放置在图像顶部时，请将Utility 组件中的.uk-inline class添加到图片以及内容的父容器元素中，以创建定位上下文。

Note 该组件通常用于Overlay 组件中的遮罩层。使用Inverse 组件中的 .uk-light 或 .uk-dark class 可以应用浅色或深色，以在深色或浅色背景上有更好的可见性。

Class Description
.uk-position-top 定位到顶部
.uk-position-left 定位到左侧
.uk-position-right 定位到右侧
.uk-position-bottom 定位到底部 
<div class="uk-inline">

    <!-- Place any content, like an image, here -->

    <div class="uk-position-center"></div>

</div>
  • Top
    Bottom
    Left
    Right
  • <div class="uk-inline uk-margin">

    <img src="/skin/ukv3/images/photo.jpg" alt="">

    <div class="uk-position-top uk-overlay uk-overlay-default uk-text-center">Top</div>
    <div class="uk-position-bottom uk-overlay uk-overlay-default uk-text-center">Bottom</div>
    <div class="uk-position-left uk-overlay uk-overlay-default uk-flex uk-flex-middle">Left</div>
    <div class="uk-position-right uk-overlay uk-overlay-default uk-flex uk-flex-middle">Right</div>

</div>

X 和 Y 方向

您还可以添加以下class之一，应用更具体的定位效果。

Class Description
.uk-position-top-left 放置在左上角
.uk-position-top-center 放置在顶部居中
.uk-position-top-right 放置在右上角
.uk-position-center 放置在水平和垂直方向的中心位置
.uk-position-center-left 放置在左侧垂直居中位置
.uk-position-center-right 放置在右侧垂直居中位置
.uk-position-bottom-left 放置在左下角
.uk-position-bottom-center 放置在底部居中位置
.uk-position-bottom-right 放置在右下角 
<div class="uk-position-top-right"></div>
  • Top Left
    Top Center
    Top Right
    Center Left
    Center
    Center Right
    Bottom Left
    Bottom Center
    Bottom Right 
  • <div class="uk-inline">

    <img src="/skin/ukv3/images/photo.jpg" alt="">

    <div class="uk-position-top-left uk-overlay uk-overlay-default">Top Left</div>
    <div class="uk-position-top-center uk-overlay uk-overlay-default">Top Center</div>
    <div class="uk-position-top-right uk-overlay uk-overlay-default">Top Right</div>
    <div class="uk-position-center-left uk-overlay uk-overlay-default">Center Left</div>
    <div class="uk-position-center uk-overlay uk-overlay-default">Center</div>
    <div class="uk-position-center-right uk-overlay uk-overlay-default">Center Right</div>
    <div class="uk-position-bottom-left uk-overlay uk-overlay-default">Bottom Left</div>
    <div class="uk-position-bottom-center uk-overlay uk-overlay-default">Bottom Center</div>
    <div class="uk-position-bottom-right uk-overlay uk-overlay-default">Bottom Right</div>

</div>

覆盖

如果希望定位的元素覆盖它的容器，只需添加.uk-position-cover class。

<div class="uk-position-cover"></div>
  • Cover
  • <div class="uk-inline">

    <img src="/skin/ukv3/images/photo.jpg" alt="">

    <div class="uk-position-cover uk-overlay uk-overlay-default uk-flex uk-flex-center uk-flex-middle">Cover</div>

</div>

放在外面

有两个class可将元素居中放置在父容器的左侧和右侧的外面。这对于需要将Slidenav 组件放置在Slideshow组件 或 Slider组件外部的时候非常有用。

Class Description
.uk-position-center-left-out 将元素放置在左侧外部的垂直居中位置。
.uk-position-center-right-out 将元素放置在右侧外部的垂直居中位置。

Note 一旦外部定位的元素向右伸出视口，将导致出现水平滚动条。使用“Visibility 组件可以在较小的视口中隐藏超出到外部的元素，只显示位于内部的元素。

<div class="uk-position-center-left-out"></div>
  • Out
    Out
  • <div class="uk-inline">

    <img src="/skin/ukv3/images/photo.jpg" alt="">

    <div class="uk-position-center-left-out uk-overlay uk-overlay-primary uk-visible@s">Out</div>
    <div class="uk-position-center-right-out uk-overlay uk-overlay-primary uk-visible@s">Out</div>

</div>

小型 margin

要对定位的元素应用较小的margin，请添加.uk-position-small class。

<div class="uk-position-small uk-position-center"></div>
  • Top Left
    Top Center
    Top Right
