由于Webkit-line-clamp仅适用于chrome,我试图实现适用于所有浏览器的相同功能。
如果有超过4行,我隐藏剩余内容并添加省略号,但问题是如果少于4行,则省略号即将到来,其高度为4行。我想要它只有超过4行
.line-clamp
{
display : block;
display : -webkit-box;
-webkit-box-orient : vertical;
position : relative;
line-height : 1.2;
overflow : hidden;
text-overflow : ellipsis;
padding : 0 !important;
}
.line-clamp:after
{
content : '...';
text-align : right;
bottom : 0;
right : 0;
width : 25%;
display : block;
position : absolute;
height : calc(1em * 1.2);
background : linear-gradient(to right, rgba(255, 255, 255, 0), rgba(255, 255, 255, 1) 75%);
}
.line-clamp-4
{
height : calc(1em * 1.2 * 4);
}

<p id="FirstDiv" class="line-clamp line-clamp-4">This is a cross-browser (pure CSS) solution that will clamp text to X number of lines with a trailing ellipsis in Webkit browsers. The `height` property is used on other browsers (along with a fading text effect) as a graceful fallback in non-Webkit browsers. The use of CSS `calc` allows for any font-size to work properly; i.e. you don't need a fixed height or a fixed font size for this to work! Play with it :-) You can change the second class to `line-clamp-[1|2|3|4|5]` and experiment with this just a little.</p>

我可以用这个代码做什么,或者有什么方法可以实现这个,就像在所有浏览器中使用line-clamp一样?
