自定义如何为文本加下划线

Question

如何在图像中获得边框底部。我使用h1属性尝试了text-decoration标记的文字下划线。

h1 {
  color: #F16A70;
  text-transform: uppercase;
  font-size: 30;
  font-family: oswald text-decoration: underline;
}
h1:after {
  width: 60%;
  border-bottom: 2px solid #F16A70;
}

<div>
  <h1>navigation</h1>
</div>

Answer 1

这是另一个解决方案：

＆＃13;

＆＃13;

h1{
    color: #F16A70;
    text-transform: uppercase;
    display: inline-block;
    font-size: 30;
    font-family: oswald;
    text-decoration: none;
    background-image: linear-gradient(to right, #F16A70, #F16A70);
    background-position: bottom left;
    background-repeat: no-repeat;
    background-size: 50% 2px;
    transition: background-size .5s ease;
}
h1:hover {
    background-size: 100% 2px;
}

＆＃13;

<div>
<h1>navigation</h1>
</div>

你可以使用css3 linear-gradient()来完成。

<强>步骤：

1. 使用linear-gradient()创建背景图片。
2. 使用css background-size属性调整其大小。
3. 将其放置在具有background-position css属性的元素的左下角位置。

必要的CSS：

h1 {
  background: linear-gradient(to right, #F16A70, #F16A70) no-repeat;
  background-size: 60% 3px;
  background-position: left bottom;
}

h1 {
  background: linear-gradient(to right, #F16A70, #F16A70) no-repeat;
  background-size: 60% 3px;
  background-position: left bottom;
  color: #F16A70;
  text-transform: uppercase;
  font-size: 30px;
  font-family: oswald, sans-serif;
  display: inline-block;
  vertical-align: top;
  padding-bottom: 10px;
}

<h1>Navigation</h1>

尝试这个：

.navigation-heading h1{
  display:inline-block;
            color: #F16A70;
            text-transform: uppercase;
            font-size: 30px;
            font-family: 'oswald';
  position:relative;
        }

h1:after{
  content:'';
  position:absolute;
  top:100%;
  left:0;
  width:65%;
  border-bottom: 2px solid #F16A70;
  }

<div class="navigation-heading">
<h1>navigation</h1>
</div>

Answer 5

您可以使用Flexbox和:after伪元素。

＆＃13;

＆＃13;

h1 {
  color: #F16A70;
  text-transform: uppercase;
  font-size: 30;
  font-family: sans-serif;
  display: inline-flex;
  flex-direction: column;
}
h1:after {
  width: 60%;
  border-bottom: 2px solid #F16A70;
  content: '';
}

＆＃13;

<h1>navigation</h1>

＆＃13;

＆＃13;

＆＃13;

您还可以使用relative/absolute位置来定位伪元素。

＆＃13;

＆＃13;

h1 {
  color: #F16A70;
  text-transform: uppercase;
  font-size: 30;
  font-family: sans-serif;
  position: relative;
  display: inline-block;
}
h1:after {
  width: 60%;
  border-bottom: 2px solid #F16A70;
  content: '';
  position: absolute;
  bottom: 0;
  left: 0;
}

＆＃13;

<h1>navigation</h1>

＆＃13;

＆＃13;

＆＃13;

Answer 6

h1:after {
    content : "";
    width   : 50%;  /* you can set here the length of border */
    border-bottom:1px solid #f16a70;
}

更新h1:after css
