回答1：

1、打开html开发工具，新建一个html文件在html代码页面创建一个

并给这个标签添加一个类名linear：

2、然后为类设置样式。在title后面创建一个style标签，然后在这个标签里面设置linear类的高、渐变（linear-gradient）的样式，这里的第一个参数是设置渐变的方向，后面两个参数是起始颜色和终止颜色。设置好后去浏览器查看效果：

3、保存好html文件后使用浏览器查看效果。就会看到一个绿色到红色的渐变了。以上就是html中让背景颜色渐变的设置方法介绍：

html中让背景颜色渐变步骤如下：

1、打开html开发工具，新建一个html文件。

2、在html代码页面创建一个

并给这个标签添加一个类如：linear。如图代码：
。

3、为类设置样式。在后面创建一个<style>标签，然后在这个标签里面设置linear类的高、渐变（linear-gradient）的样式。演示中设置的渐变黑白渐变。如图：</p> <p>代码：</p> <p><style type="text/css"></p> <p>.linear{</p> <p>background-image: linear-gradient(to top, #fff,#000);</p> <p>height: 300px;</p> <p>}</p> <p></style></p> <p><img loading="lazy" class="ikqb_img"

src="/picurl?url=https%3A%2F%2Fiknow-pic.cdn.bcebos.com%2F8d5494eef01f3a299c0b37849725bc315d607cbd%3Fx-bce-process%3Dimage%252Fresize%252Cm_lfit%252Cw_600%252Ch_800%252Climit_1%252Fquality%252Cq_85%252Fformat%252Cf_auto"

src="/picurl?url=https%3A%2F%2Fiknow-pic.cdn.bcebos.com%2F203fb80e7bec54e7aceef754b7389b504fc26a7e%3Fx-bce-process%3Dimage%252Fresize%252Cm_lfit%252Cw_600%252Ch_800%252Climit_1%252Fquality%252Cq_85%252Fformat%252Cf_auto" esrc="https://iknow-pic.cdn.bcebos.com/203fb80e7bec54e7aceef754b7389b504fc26a7e"></p> <p>4、然后设置div的background属性，如图所示，背景颜色渐变使用-webkit-linear-gradient。</p> <p><img loading="lazy" class="ikqb_img" src="/picurl?url=https%3A%2F%2Fiknow-pic.cdn.bcebos.com%2Ffaedab64034f78f0e76877b977310a55b3191c1c%3Fx-bce-process%3Dimage%252Fresize%252Cm_lfit%252Cw_600%252Ch_800%252Climit_1%252Fquality%252Cq_85%252Fformat%252Cf_auto" esrc="https://iknow-pic.cdn.bcebos.com/faedab64034f78f0e76877b977310a55b3191c1c"></p> <p>5、接下来，在-webkit-linear-gradient中写入顶部，从顶部到底部设置渐变。这里需要注意的是，如果你写的是顶部，不要写下底部。</p> <p><img loading="lazy"

<p>css3可以直接设置背景变色。<br>这是IE的代码<br>body<br>{<br>filter:progid:DXImageTransform.Microsoft.gradient(startcolorstr=red,endcolorstr=blue,gradientType=1);<br>}<br>代码主要有三个参数，依次是：startcolorstr, endcolorstr, 以及gradientType。<br>其中gradientType=1代表横向渐变，gradientType=0代表纵向淅变。startcolorstr=”色彩” 代表渐变渐变起始的色彩，endcolorstr=”色彩” 代表渐变结尾的色彩。<br>Firefox或是Safari浏览器的代码：<br>filter:alpha(opacity=100 finishopacity=0 style=1 startx=0,starty=5,finishx=90,finishy=60)<br>opacity表示透明度，默认的范围是从0 到 100，finishopacity 是一个可选参数，如果想要设置渐变的透明效果，就可以使用他们来指定结束时的透明度。范围也是0 到 100。style用来指定透明区域的形状特征：0 代表统一形状，1 代表线形，2 代表放射状，3 代表矩形。startx 渐变透明效果开始处的 X坐标。 starty 渐变透明效果开始处的 Y坐标。 finishx 渐变透明效果结束处的 X坐标。 finishy 渐变透明效果结束处的 Y坐标。<br>自己试试，这些都是网上有的，我试过，还可以，但是要比较新的浏览器，IE要IE8以上吧。谷歌浏览器还好点。我觉得为了IE8以下的浏览器也能有渐变的效果还是用图片比较好，毕竟还有很多人用IE6、IE7的</p> </div>
