HTML Css位置绝对不工作[重复]

问题描述 投票:0回答:1

这个问题与以下内容完全相同:

如何将这些按钮完全保留在背景图像的框中?当您调整窗口/浏览器的大小时,它们的位置/大小会发生变化,并且它们不再适合背景图像框。

html, body {
    margin: 0;
}

.Div1 {
    background-image: url("https://imgur.com/7NQ3IOt.jpg");
    background-size: 100% 100%;
    background-repeat: no-repeat;

    position: relative;
    height: 76.1vw;
}

.Div2 {
    background-image: url("https://imgur.com/CjVMSqG.jpg");
    background-size: 100% 100%;
    background-repeat: no-repeat;

    position: relative;
    height: 169vw;
}

.Btns {
    position: absolute;
    font-size: 1.9vw;
    left: 17.4vw;
    width: 26.3vw;
}

我认为这里的问题是按钮的测量和默认填充,边框和浏览器特定样式。我通过一些手动调整编辑了计算值的小提琴:

简而言之,填充也应该是vw单位,并设置-webkit-appearance: none;

你可以在这里看到CodePen:

    font-size: 1.8vw;
    box-sizing:  border-box; 
    padding:  .25vw 0;

    width: 26.75vw; 
    -webkit-appearance:  none;  
    
}
