[英]How to hide nested element when parents width is 0?
我試圖在其父寬度為0時隱藏嵌套的p標簽。從本質上講,我希望嵌套的p標簽在寬度接近0以及展開時跟隨父元素。 我敢肯定,這很簡單,感謝您的提前幫助。
HTML:
<div class="container">
<div class="floater1">
<p id="icon">X</p>
</div>
<div class="floater2">
<p>This is a test</p>
</div>
</div>
<button>click</button>
CSS:
.container {
width: 100%;
height: 35px;
border: 1px solid #000;
}
.floater1 {
float: left;
width: 0px;
height: inherit;
background: red;
text-align: center;
transition: width 200ms ease-in-out;
}
.show {
width: 30px;
}
.floater2 {
height: inherit;
background: yellow;
overflow: hidden;
padding-left: 15px;
}
p {
margin: 0;
line-height: 35px;
}
JS:
var trigger = $('button');
var deleteBtn = $('.floater1');
trigger.click(function(){
console.log("hello")
deleteBtn.toggleClass('show');
})
您必須設置overflow:hidden; 屬性為".floater1"
類。 這樣,當父級寬度為0時,p標簽將被隱藏。
var trigger = $('button'); var deleteBtn = $('.floater1'); trigger.click(function(){ console.log("hello") deleteBtn.toggleClass('show'); })
.container { width: 100%; height: 35px; border: 1px solid #000; } .floater1 { float: left; width: 0px; height: inherit; background: red; text-align: center; transition: width 200ms ease-in-out; overflow:hidden; } .show { width: 30px; } .floater2 { height: inherit; background: yellow; overflow: hidden; padding-left: 15px; } p { margin: 0; line-height: 35px; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="container"> <div class="floater1"> <p>X</p> </div> <div class="floater2"> <p>This is a test</p> </div> </div> <button>click</button>
在這里看到工作的小提琴
只需將這些添加到您的CSS:
.floater1 p {
opacity: 0;
transition: opacity 250ms ease;
}
.floater1.show {
width: 30px;
}
.show p {
opacity: 1;
}
希望對您有所幫助!
