Question

我有一些隐藏和显示文字的代码依赖于标记<section>。

显示第二部分隐藏，直到点击显示按钮。

根据字符编号，我无法弄清楚如何制作

例如，显示前100个字符，当点击按钮显示时，它显示文本的其余部分。

这是我的代码

HTML

<article>
<input type="checkbox" id="read_more" role="button">
<label for="read_more" onclick=""><span>Show</span><span>Hide</span></label>     
<figure>
<img src="HERE MUST BE A IMAGE.jpg" alt="" />
</figure>

<section>

和CSS

figure {
    margin: 0 0 1.3rem 0;
    -webkit-transition: .125s linear;
    -moz-transition: .125s linear;
    -ms-transition: .125s linear;
    -o-transition: .125s linear;
    transition: .125s linear;
}

figure img {
    max-width: 100%;
    height: auto;
}



body:before, body:after {
    content: "";
    display: table;
}

body:after { clear: both }

p { margin-bottom: 1.3rem }

article {
    margin-bottom: 3rem;
    position: relative;
    *zoom: 1;
}

article:before, article:after {
    content: "";
    display: table;
}

article:after { clear: both }

article figure {
    float: left;
    width: 32.5%;
}

article section:first-of-type {
    float: right;
    width: 62.5%;
}

article section:last-of-type {
    display: none;
    visibility: hidden;
}

section {
    -webkit-transition: .125s linear;
    -moz-transition: .125s linear;
    -ms-transition: .125s linear;
    -o-transition: .125s linear;
    transition: .125s linear;
}

input[type=checkbox] {
    border: 0;
    clip: rect(0 0 0 0);
    height: 1px;
    width: 1px;
    margin: -1px;
    overflow: hidden;
    padding: 0;
    position: absolute;
}

[for="read_more"] {
    position: absolute;
    bottom: -3rem;
    left: 0;
    width: 100%;
    text-align: center;
    padding: .65rem;
    box-shadow: inset 1px 1px rgba(0, 0, 0, 0.1), inset -1px -1px rgba(0, 0, 0, 0.1);
}

[for="read_more"]:hover {
    background: rgba(0,0,0,.5);
    color: rgb(255,255,255);
}

[for="read_more"] span:last-of-type {
    display: none;
    visibility: hidden;
}

input[type=checkbox]:checked ~ section {
    display: block;
    visibility: visible;
    width: 100%;
}

input[type=checkbox]:checked ~ figure { width: 100% }

input[type=checkbox]:checked ~ [for="read_more"] span:first-of-type {
    display: none;
    visibility: hidden;
}

input[type=checkbox]:checked ~ [for="read_more"] span:last-of-type {
    display: block;
    visibility: visible;
}

Here is jsfiddle example

谢谢

使用纯CSS无法做到这一点。

你需要JavaScript（例如jQuery很适合这个）来进行字符计数，然后根据这些规则应用CSS。

显示/隐藏（阅读更多）文本取决于字符纯CSS的数量
