响应对角线css

我需要帮助在css中设置对角线以适应移动设备的多种分辨率。 这是一个100%宽度的div和一条对角线,它应该保持在div内部,但每次我改变窗口的分辨率时,线条会向上或向下移动。 必须有我能做的事情。

以下是一个例子:

.wrapper
{
width: 100%;
position: relative;
border: 1px solid red;
overflow: hidden;
padding-bottom: 12px;
}
.upper-triangle
{
-moz-transform: rotate(-3.5deg);
-o-transform: rotate(-3.5deg);
-webkit-transform: rotate(-3.5deg);
-ms-transform: rotate(-3.5deg);
transform: rotate(-3.5deg);
border-color: black;
border-style: solid;
border-width:2px;
position: relative;
top: -21px;
zoom: 1;
width: calc(100% - -2px);
right: 1px;
}
.arrow-wrapper
{
position: absolute;
top: 41px;
left: 22px;
z-index: 1;
}
.arrow-wrapper::before
{
border-style: solid;
border-width: 16px 0px 0px 20px;
border-color: transparent transparent transparent black;
position: absolute;
content: "";
}
.arrow-wrapper::after
{
position: absolute;
content: "";
width: 0;
height: 0;
margin-top: 8px;
margin-left: 4px;
border-style: solid;
border-width: 16px 0 0 20px;
border-color: transparent transparent transparent white;
}

HTML:

<div class="wrapper">
    <div class="headline">
        <img class="image" width="36" height="36"/>
    </div>

您需要设置定位点以应用旋转。你的变换正在改变位置,因为它默认从中心转向,在这种情况下不是你想要的。

在你的css中使用:

.upper-triangle {
  ...
  -webkit-transform-origin: 0% 0%;
  transform-origin: 0% 0%;
  ...
}

注意:在你的小提琴中,我必须将top更改为10px

也许这样的作品? fiddle

<script>
$(document).ready(function(){
var viewportHeight = $(window).height();
var viewportWidth = $(window).width();

var width = viewportWidth;
var height = viewportHeight*0.6;

var imgSize = "100%" + ' ' + "100%";

$('.div').css("width", width);
$('.div').css("height", height);
$('.div').css("background-size", imgSize);
});

$(window).resize(function(){
var viewportHeight = $(window).height();
var viewportWidth = $(window).width();

var width = viewportWidth;
var height = viewportHeight*0.6;
var imgSize = width + ' ' + height;

$('.div').css("width", width);
$('.div').css("height", height);
$('.div').css("background-size", imgSize);
});

</script>

<style>
.div { background-image: url('http://indesignsecrets.com/wp-content/uploads/2010/07/step_1.jpg'); background-position: left top; background-repeat: no-repeat; background-color: yellow; }
</style>

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

最好使用 SVG,它提供了很好的响应对角线,几乎适用于所有浏览器。

.box {
    width: 20rem;
    height: 10rem;
    background-color: hsla(0, 0%, 70%, 0.3);
    cursor: pointer;
    position: relative;
}

.svg-stroke {
    position: absolute;
    width: 100%;
    height: 100%;
}
<div class="box">
    <svg class='svg-stroke' viewBox='0 0 10 10' preserveAspectRatio='none'>
        <line x1='0' y1='0' x2='10' y2='10' stroke='red' stroke-width='.6' stroke-opacity='0.2' />
        <line x1='10' y1='0' x2='0' y2='10' stroke='red' stroke-width='.6' stroke-opacity='0.2' />
    </svg>
</div>
