CSS:从右到左展开a<div>以显示文本

expand hover flexbox css jquery

JoSch · 技术社区 · 6 年前

我想建立一个固定的 <div> ,包含一个图标,当将鼠标悬停在 <部门> 展开,而不是图标),在图标左侧显示一段文本。图标的位置保持不变。下面是一个草图来帮助说明我想做什么:

<部门> <span> <部门> flex . 在展开/悬停状态下,事情看起来应该是这样的,但是一旦 < 再次缩小,包含图标和文本的两个div尝试共享剩下的小空间,因此图标被切断,文本被压扁。

如果有人能帮我弄清楚我想怎么做,我会很感激的。

$(document).ready(function() {
  var button = $("#myButton");

  button.mouseenter(function() {
    $(this).addClass("grow");
  });
  button.mouseleave(function() {
    $(this).removeClass("grow");
  });
});

.button-container {
  position: fixed;
  top: 5%;
  right: 5%;
  width: 100px;
  padding: 5px;
  background-color: tomato;
  display: flex;
  justify-content: space-between;
  overflow: hidden;
  transition: width 1s;
}

.button-container.grow {
  width: 300px
}

.button-text-container {
  display: flex;
  align-items: center;
  justify-content: center;
  background-color: lightblue;
}

.button-icon-container {
  height: 100%;
  display: flex;
  align-items: center;
  justify-content: center;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="button-container" id="myButton">

  <div class="button-text-container">
    <span>Here comes some text.</span>
  </div>

  <div class="button-icon-container">
    <img src="https://placeholder.pics/svg/100x100/7AFFA6/000000/ICON">
  </div>

</div>

只有 CSS如果你依赖flexbox order 您可以将宽度更改移动到文本而不是父容器:

.button-container {
  position: fixed;
  top: 5%;
  right: 5%;
  padding: 5px;
  background-color: tomato;
  display: flex;
  justify-content: space-between;
  overflow: hidden;
}


.button-text-container {
  order:-1;
  display: flex;
  align-items: center;
  justify-content: center;
  background-color: lightblue;
  white-space:nowrap; /*Keep text always one line*/
  overflow:hidden;
  width:0;
  transition: width 1s;
}

.button-icon-container {
  height: 100%;
  display: flex;
  align-items: center;
  justify-content: center;
}
.button-icon-container:hover + .button-text-container {
  width:200px;
}

<div class="button-container" id="myButton">
  <div class="button-icon-container">
    <img src="https://placeholder.pics/svg/100x100/7AFFA6/000000/ICON">
  </div>
  
  <div class="button-text-container">
    <span>Here comes some text.</span>
  </div>
</div>
