在手机中点击即可显示工具提示。问题是当它到达屏幕的末端时,工具尖端会切断。当我点击屏幕顶部的图标时,工具提示会显示在图标顶部而不是底部。

我尝试过编辑代码。 此外,如果您想在移动视图中使用特定位置,可以使用
@media only screen and (max-width: 500px){
[data-tooltip]:before {//left:"some value";right:"some value";}[data-tooltip]:after{
bottom: 227%;
left: 50%;
margin-left: 26px;}
}
/* Add this attribute to the element that needs a tooltip */
[data-tooltip] {
position: relative;
z-index: 2;
cursor: pointer;
}
/* Hide the tooltip content by default */
[data-tooltip]:before, [data-tooltip]:after {
visibility: hidden;
-ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";
filter: progid:DXImageTransform.Microsoft.Alpha(Opacity=0);
opacity: 0;
pointer-events: none;
}
/* Position tooltip above the element */
[data-tooltip]:before {
position: absolute;
bottom: 150%;
left: 50%;
margin-bottom: 5px;
margin-left: -9em;
padding: 7px;
width: 160px;
-webkit-border-radius: 3px;
-moz-border-radius: 3px;
border-radius: 3px;
background-color: #000;
background-color: hsla(0, 0%, 20%, 0.9);

content: attr(data-tooltip);
text-align: center;
font-size: 14px;
line-height: 1.2;
}
/* Triangle hack to make tooltip look like a speech bubble */
[data-tooltip]:after {
position: absolute;
bottom: 150%;

margin-left: -5px;

font-size: 0;

}
/* Show tooltip content on hover */
[data-tooltip]:hover:before, [data-tooltip]:hover:after {

-ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=100)";
