css 文字两端对齐

1.利用 text-align: justify;属性使文字两端对齐

// css
.justify-w4 {
  text-align: justify;
  width: 70px;
  display: inline-block;
  height: 18px;
}

.justify-w4::after {
  content: "";
  display: inline-block;
  width: 100%;
}

<-- HTML -->
<p><span class="justify-w4">电视机</span></p>
<p><span class="justify-w4">性感漂亮</span></p>
<p><span class="justify-w4">手机</span></p>

2.利用letter-spacing

// css
.w4 {
  text-align: center;
  width: 4em;
}
.w2{
letter-spacing:2em; /*如果需要y个字两端对齐，则为(x-y)/(y-1),这里是（4-2）/(2-1)=2em */
margin-right:-2em; /*同上*/
}
.w3{
letter-spacing:0.5em; /*如果需要y个字两端对齐，则为(x-y)/(y-1),这里是（4-3）/(3-1)=0.5em */
margin-right:-0.5em; /*同上*/
}

<-- HTML -->
<p><span class="w3">电视机</span></p>
<p><span class="w4">性感漂亮</span></p>
<p><span class="w2">手机</span></p>
