CSS星空背景动画导致页面href链接失效的问题求助

给HTML页面添加CSS星空背景动画后，所有href书签及外部链接均无法点击。移除动画元素（HTML第7-13行）后链接恢复正常，调整动画元素位置无效，求解决办法。

绝对定位的#space和.stars元素铺满了整个视口，且设置了较高的z-index:99——即便元素处于透明状态，也会阻挡下方元素的鼠标点击事件，导致链接无法被触发。

给星空容器添加pointer-events: none;属性，让它不拦截任何鼠标事件，事件会直接穿透到下方的链接元素上。同时修正HTML中的标签语法错误。

修改后的HTML代码 #

<html>
  <br>
  <br>
 
  <div id="space">
    <div class="stars"></div>
    <div class="stars"></div>
    <div class="stars"></div>
    <div class="stars"></div>
    <div class="stars"></div>
  </div>
  
  <div>
    <p style="color:orange;background-color:green;text-align:center;font-size:55px;">Page Title</p>
    <p style="color:white;text-align:center;font-size:25;">this is what it's about</p>
    <br> <br>
    <p style="color:orange;text-align:center;font-size:35;">I can add a link right <a href="#new_section">Here</a></p>
  </div>
  <br> <br><br> <br><br> <br><br> <br><br> <br><br> <br><br> <br><br> <br><br> <br><br> <br><br> <br>
  
  <p style="color:orange;text-align:center;font-size:35;">this is a bookmark</p>
  
  <a id="new_section">new section</a>
</html>

#space, .stars {
  overflow: hidden;
  position: absolute;
  top: 0;
  bottom: 0;

  left: 0;
  right: 0;
  pointer-events: none; /* 添加这行实现事件穿透 */
}

.stars {
  background-image:
    radial-gradient(2px 2px at 20px 30px, #eee, rgba(0,0,0,0)),
    radial-gradient(2px 2px at 40px 70px, #fff, rgba(0,0,0,0)),
    radial-gradient(2px 2px at 50px 160px, #ddd, rgba(0,0,0,0)),
    radial-gradient(2px 2px at 90px 40px, #fff, rgba(0,0,0,0)),
    radial-gradient(2px 2px at 130px 80px, #fff, rgba(0,0,0,0)),
    radial-gradient(2px 2px at 160px 120px, #ddd, rgba(0,0,0,0));
  background-repeat: repeat;
  background-size: 200px 200px;
  animation: zoom 5s infinite;
  opacity: 0;
}

.stars:nth-child(1) {
  background-position: 50% 50%;
  animation-delay: 0s;
}
.stars:nth-child(2) {
  background-position: 20% 60%;
  animation-delay: 1s;

.stars:nth-child(3) {
  background-position: -20% -30%;
  animation-delay: 2s;

.stars:nth-child(4) {
  background-position: 40% -80%;
  animation-delay: 3s;
}
.stars:nth-child(5) {
  background-position: -20% 30%;
  animation-delay: 4s;
}

@keyframes zoom {
  0% {
    opacity: 0;
    transform: scale(0.5);
    animation-timing-function: ease-in;
  } 
  85% {
    opacity: .75;
    transform: scale(2.8);
    animation-timing-function: linear;
  }
  100% {
    opacity: 0;
    transform: scale(3.5);
  }
}

额外说明 #

• pointer-events: none; 会让元素完全忽略鼠标事件（点击、悬停等），事件会直接作用于其下方的元素。
• 修正了HTML中错误的div>标签为<div>，避免页面结构混乱。
