Question

我正在尝试在我的网站上编写此发现菜单部分的代码，一切都进行得很好，除了一件事情是，当我单击Js激活View more按钮但项目缩小时，我不知道为什么我试图将宽度设置为100％，但不起作用。我在这里搜索了堆栈溢出一点点，但没有发现任何帮助这是我的代码：

.discover-ou-menu{
position: relative;

}
.section-heading{
  text-align: center;
  font-family: 'Roboto', sans-serif;
text-transform:capitalize;
margin: 0;
}
.section-heading::after{
  content: "";
  position: relative;
  left: 41rem;
  display: block;
  width: 50px;
  height: 5px;
  text-align: center;
  background-color: #ff9900;
  margin-bottom: 1.5rem;
  margin: 0;
}
/* .dom-container{
  position: relative;
} */
.nav-menu{
  text-align: center;
  padding-left: 16px;
  font-family: 'Roboto', sans-serif;
  font-weight: bold;
  text-transform: capitalize;
  font-size: 15px;
  margin-top: 5px;
  margin-bottom: 40px;
}
.nav-menu-item{

  color: black;
  padding-right: 20px;
}
.menu{

下面是我点击“查看更多”按钮的“ 之前”和“ 之后”

的一些屏幕截图

之前

之后

Answer 1

只需在main元素和第n个子元素上使用一个类将其隐藏即可，而不是将它们包装起来。

document.querySelector("button").addEventListener("click", function () {
  document.querySelector('.table').classList.toggle('limited');
})

.table.limited .tr:nth-of-type(1n+4) {display: none;}

<div class="table limited">
  <div class="tr">1
  </div>
  <div class="tr">2
  </div>
  <div class="tr">3
  </div>
  <div class="tr">4
  </div>
  <div class="tr">5
  </div>
  <div class="tr">6
  </div>
</div>
<button class="more">more</button>

带有动画

document.querySelector("button").addEventListener("click", function() {
  document.querySelector('.table').classList.toggle('limited');
})

.table.limited .tr:nth-of-type(1n+4) {
  max-height: 0;
  overflow: hidden;
  opacity: 0;
}

.table .tr:nth-of-type(1n+4) {
  opacity: 1;
  transition: all 1s ease-in;
  max-height: 100em;
}

<div class="table limited">
  <div class="tr">1
  </div>
  <div class="tr">2
  </div>
  <div class="tr">3
  </div>
  <div class="tr">4
  </div>
  <div class="tr">5
  </div>
  <div class="tr">6
  </div>
</div>
<button class="more">more</button>

Answer 2

替换

.tr {
    display: table-row;
}

与此

.tr {
    display: table-row;
    float: left;
}

然后尝试

防止元素缩小
