Question

我正在制作动画，当我们将鼠标悬停在三角形上时，三角形会移动并显示之前隐藏的内容。

它工作正常，但没有响应，在我的电脑上很好但是当我调整窗口大小时，三角形出现在屏幕中间或随机位置，我怎么能保持位置，以便只有黑色三角形可见？

我的代码，以防万一：

body{
    height:100%;
    background-color: grey;
}

/* AVISO :: Começo da animação trianglo lado esquerdo :: AVISO  */

#container {
	top:35%;
	margin-left: -19.5%;
	background-color: transperent;
	width:355px;
}

.pencil-body {
	  background-color: red;
	  display: inline-block;
	  padding: 75px;
	  width: 100px;
}

.pencil-tip {
	  width: 0;
	  height: 0;
	  border-top: 75px solid transparent;
	  border-left: 100px solid black;
	  border-bottom: 75px solid transparent;
	  display: inline-block;
}

#container:hover {
    transform: translate(200px,0);
    -webkit-transform: translate(200px,0); /** Chrome & Safari **/
}

/* AVISO :: Fim da animação trianglo lado esquerdo :: AVISO  */

/* AVISO :: Começo da animação trianglo lado direito :: AVISO  */

#container2 {
	float:right;
	margin-left:92.5%;
	top:35%;
	width:355px;
}

.pencil-body2 {
	float:right;
	  background-color: red;
	  display: inline-block;
	  padding: 75px;
	  width: 100px;
}

.pencil-tip2{
	  width: 0;
	  height: 0;
	  border-top: 75px solid transparent;
	  border-right: 100px solid black;
	  border-bottom: 75px solid transparent;
}

#container2:hover {
    transform: translate(-200px,0);
    -webkit-transform: translate(0px,200); /** Chrome & Safari **/
}

/* AVISO :: Fim da animação trianglo lado direito :: AVISO  */

.animation {
    position: absolute;
    transition: all 2s ease-in-out;
    -webkit-transition: all 2s ease-in-out; /** Chrome & Safari **/
}

Answer 1

你应该使用

left: -255px;

和

right: -255px;

而不是使用边距。

例如：

#container {
    left: -255px;
}

#container2 {
    right: -255px;
}

如果可以，你应该使用html5。这是基本设置

<!DOCTYPE html>
<html>
    <head>
       <meta charset="UTF-8>
       <title>title</title>
    </head>
    <body>
        ...
    </body>
</html>
