截斷文本問題

單行文本截斷

p {
    overflow: hidden;
    text-overflow: ellipsis;
    white-space: nowrap;
}

多行文本截斷

對於固定行高的文本框,咱們能夠使用純 CSS 來截斷,思路是使用 float 屬性,讓另外一個元素覆蓋掉最後的地方

爲了方便理解,添加了背景色區分每一塊css

<div class="container">
    <div class="content">
        Responsive layouts in material design adapt to any possible screen size. This UI guidance includes a flexible
        grid that ensures consistency across layouts, breakpoint details about how content reflows on different screens,
        and a description of how an app can scale from small to extra-large screens.
    </div>
</div>

<style>
.container {
    height: 200px;
    width: 200px;
    background-color: beige;
    overflow: hidden;
}

.container::before {
    content: "";
    height: 100%;
    width: 1em;
    float: left;
    background-color: #adcfea;
}

.container::after {
    content: "...";
    text-align: right;
    background-color: lightblue;

    height: 1em;
    width: 2em;
    margin-left: -1em;

    float: right;
    position: relative;
    top: -1em;
    left: calc(100% - 1em);
}

.content {
    width: 100%;
    margin-left: -1em;
    float: right;
}
</style>

flexbox 中截斷文本的問題

<div style="display:flex;">
    <div class="fc">            
        <p>blablablablablablablablabla...blablablablablablablabla</p>
    </div>
    <div class="fc">            
        <p>blablablablablablablablabla...blablablablablablablabla</p>
    </div>
</div>

<style>
    p {
        overflow: hidden;
        text-overflow: ellipsis;
        white-space: nowrap;
    }
</style>

咱們指望的效果是兩個文本在同一行各佔百分之五十,溢出的文本被 ...截斷,但實際的效果是兩段文字都在同一排完整的顯示出來了。(Safari不會出現這種問題)flex

解決方案是對 .fc 設置 width(或 max-widthmin-width) 或 overflow 屬性ui

加上flexbox

.fc {
    width: 50%;
}

或者spa

.fc {
    overflow: hidden;
}

以後可獲得咱們想要的效果firefox

緣由

According to a draft spec, the above text should not fully collapse when the flex container is resized down. Because .subtitle has a width of 100%, the min-width: auto calculation that flexbox makes says that its container should be larger than we want.code

大概是 chrome、opera 以及 firefox 的默認寬度屬性的問題。blog
