各位，我创建了一组 4 个按钮(在列表中)，当用户将鼠标悬停在按钮上时，它们会显示其下方每个按钮的说明。我使用 jQuery 来切换段落元素的类以使其正常工作。我所做的工作非常好，但我只是想知道是否有一种更干净、更简单的方法可以实现 jQuery 代码，或者它是完全正常的方式吗？我非常感谢您对此的意见。提前致谢。

我的建议是在段落中使用 -data 属性来显示正确的段落，而不是为每个按钮编写一个处理程序。通过这种方式，您也不需要为每个按钮提供单独的 ID。

$('.feat-btn').hover(function(){
  var id = $(this).data('id');
  $('#' + id).toggleClass('show-blurp');
});

body{
  background-color: black;  
}

.hero-container {
  position: absolute;	
  top: 6%;	
  left: 0;	
  right: 0;		
  margin: 18% auto;
}

.hero-content {
  text-align: center;
  margin: 0 auto;
}

.hero-content li {
  display: inline-block;
}

.hero-content a {
  display: block;
  width: 200px;
  background-color: #fff;
  margin-right: 20px;
  text-align: center;
  border-radius: 5px;
}

.hero-content a {
  text-decoration: none;
}

.hero-content span {
 display: inline-block;
 margin: 40% 0;
 font-family: Sans-Serif; 
 text-transform: uppercase; 
 font-size: 1.2em;
 font-weight: 400; 
 color: blue;
  
}

.feat-blurp {
  width: 810px;
  margin: 0 auto;
  color: #fff;
  font-family: Sans-Serif;
  font-weight: lighter;
  font-size: 1.3em;
}

.hide-blurp {
  display: none;
  opacity: 0;
  transition: opacity .5s linear;
}

.show-blurp {
  display: block;
  opacity: 1;
  transition: opacity .5s linear;
  animation-name: blurp-up, blurp-fade;
  animation-duration: 1s;
  animation-fill-mode: both;
}

@keyframes blurp-up {
  from{ transform: translateY(50px)}
  to{ transform: translateY(0)}
}
@keyframes blurp-fade {
    from { opacity: 0; }
    to { opacity: 1; }
}
