当我在DIV上空盘旋时,它的高度和宽度都会增加,但我不知道如何让它更加平滑,而不是一次调整大小
function chg()
{
document.getElementById("d1").innerHTML="Great Job!";
document.getElementById("d1").style.width="300px";
document.getElementById("d1").style.height="200px";
}
function chg2()
{
document.getElementById("d1").innerHTML="Hover Over Me!";
document.getElementById("d1").style.width="230px";
document.getElementById("d1").style.height="160px";
}
div
{
background-color:RGB(177,0);
color:white;
font-size:large;
height:160px;
width:230px;
text-align:center;
line-height:150px;
}
<!DOCTYPE html> <html> <body> <div onmouSEOver="chg()" onmouSEOut="chg2()" id="d1">Hover Over Me!</div> </body> </html>
解决方法
说明
你应该看看CSS3中的过渡属性.
