我想设置一个固定的 div,其中包含一个图标,当它悬停在其上时会从右向左扩展( div展开,而不是图标),在左侧显示一段文字的图标.图标的位置保持不变.这是一个草图,以帮助说明我想做的
更改< div>的大小在悬停上没有问题,我只需添加一个宽度更大的类(包括转换动画扩展).但我对元素的定位感到困惑.我将图标和文本(在< span>内)放在单独的< div>中并尝试使用flex安排一切.在展开/悬停状态下,事情看起来应该是这样,但是一旦< div>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.
如果有人能帮助我弄清楚如何按照我希望的方式设置它,我将不胜感激.
这是我到目前为止所获得的jsFiddle:Button-GrowOnHover
加上代码本身:
$(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="http://img.558idc.com/uploadfile/allimg/210615/1T1525L2-1.jpg">
</div>
</div>
如果您依赖flexbox
order,则只能使用CSS执行此操作,并且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="http://img.558idc.com/uploadfile/allimg/210615/1T1525L2-1.jpg">
</div>
<div class="button-text-container">
<span>Here comes some text.</span>
</div>
</div>
