CSS, j's single-line, multi-line text overflow displays ellipsis-HTML Tutorial-php.cn

In the project, due to too much actual description text, the vertical length of the initial page is too long, which also reduces the utilization of the remaining information; therefore, when there is too much text, it is necessary to initialize the number of lines.

1. CSS single line text overflows and ellipses are displayed

<span style="color: #0000ff;"><</span><span style="color: #800000;">div </span><span style="color: #ff0000;">style</span><span style="color: #0000ff;">="overflow:hidden;text-overflow:ellipsis;white-space:nowrap;"</span><span style="color: #0000ff;">></span><span style="color: #000000;">

<span style="color: #0000ff;"><</span><span style="color: #800000;">div </span><span style="color: #ff0000;">style</span><span style="color: #0000ff;">="overflow:hidden;display:-webkit-box;-webkit-box-orient:vertical;-webkit-line-clamp:3;"</span><span style="color: #0000ff;">></span><span style="color: #000000;">

The above two are suitable for situations where there is only text in the label, and sometimes we will encounter such a situation

<span style="color: #0000ff;"><</span><span style="color: #800000;">div</span><span style="color: #0000ff;">></span>
    <span style="color: #0000ff;"><</span><span style="color: #800000;">p</span><span style="color: #0000ff;">></span>

3. The third way is to solve the problems encountered in the above situation

I have seen many examples on the Internet, and each has its own advantages. The one I use is a fixed line-height. The line breaks are also at a fixed height for each line, such as: line-height:20px;, and a blank line is added each time. Also let the blank line be 20px, so that we can use multiples of 20 to reasonably display the number of lines and content to be displayed

<span style="color: #0000ff;"><</span><span style="color: #800000;">div </span><span style="color: #ff0000;">class</span><span style="color: #0000ff;">="text"</span><span style="color: #0000ff;">></span>
    <span style="color: #0000ff;"><</span><span style="color: #800000;">p</span><span style="color: #0000ff;">></span><span style="color: #000000;">

In this case, line breaks will appear and blank lines will be displayed. I will leave this problem for now. I am a little tired today
