现在给一个span标签设置了如下样式: span{ display: block; word-break: break-all; width: 85px; height: 85px; margin: 14px auto; border: 2px solid transparent; text-align: center; line-height: 85px; font-size: 15px; border-radius: 100%;} 出现了一个问题,span内的设置文字数量过多之后跳出了容器之外,如何解决?

可以尝试修改 `word-break: break-all;` 为 `word-wrap: break-word;`,这样可以让单词内部换行,而不会将单词拆分。另外,如果你希望文字在超出容器宽度时显示省略号,可以尝试添加 `text-overflow: ellipsis;`。最终的样式代码如下:
```
span {
display: block;
word-wrap: break-word;
width: 85px;
height: 85px;
margin: 14px auto;
border: 2px solid transparent;
text-align: center;
line-height: 85px;
font-size: 15px;
border-radius: 100%;
overflow: hidden;
text-overflow: ellipsis;
}
```

您可以在 `<el-form>` 标签上绑定 `@input` 事件,当表单数据发生改变时,触发该事件,然后在事件处理函数中计算出水印的样式,并将样式绑定到 `<span>` 标签上。具体实现代码如下:
```
<template>
<main-content :ifDetail="true">
<div class="two-side">
<div class="main-left">
<el-form :model="form" :rules="rules" ref="form" label-width="120px" @input="handleInput">
<!-- 表单项省略 -->
</el-form>
</div>
<div class="main-right" id="show">
<div class="watermark">
<span :style="watermarkStyle" ref="showText" style="word-break:break-all;display: inline-block">{{ form.text }}</span>
</div>
</div>
</div>
</main-content>
</template>

代码中的 `watermarkStyle` 计算属性用于计算水印的样式,`handleInput` 方法用于在计算出水印样式后,将水印按照比例缩小并居中显示。注意,为了保证水印样式的正确性,需要在表单项加载完成之后计算水印样式,因此需要在 `handleInput` 方法中使用 `$nextTick` 方法等待表单项加载完成再进行计算。
span标签自动换行吗
是的,可以使用CSS中的white-space属性来实现span标签的自动换行。具体来说,可以使用normal或pre-wrap来设置换行。同时,还可以将span标签的display属性设置为block或inline-block,以便让它们具有块级元素的特性,从而实现自动换行。下面是一个示例CSS代码:
span{
border: 1px solid red;
word-break: normal;
width: auto;
display: block;
white-space: pre-wrap;
word-wrap: break-word;
overflow: hidden;
}
另外,如果是在全英文或数字状态下,也可以使用CSS中的word-wrap属性来实现span标签的自动换行。
