How to prevent child element infection for conversion scale in css3?

Question

HTML

<div class="wrapper">
    <div class="parent">
        <div class="child">
            lorem ipsum
        </div>
    </div>
</div>

CSS

.wrapper {
    width: 300px;
    height: 300px;
    margin: 30px auto;
    border: 1px dashed #ccc;
    overflow:hidden;
}

.parent {
    width: 1px;
    height: 100px;
    background-color: #f00;
    opacity: 0;
    margin: 0 auto;
    -webkit-transition: all 0.4s ease;
            transition: all 0.4s ease;
}

.wrapper:hover .parent {
    opacity: 1;
    -webkit-transform: scaleX(300);
            transform: scaleX(300);
}

.wrapper . parent .child {
    -webkit-transform: none;
            transform: none;
}

I want to scale only the .parent element when the .wrapper div hangs. But it also affects the two divs (parent and child), although it does provide the transform: none property for the .child div. How to prevent .child damage?

Answer 1

Instead transform: scaleXtry changing the width

.wrapper:hover .parent {
    opacity: 1;
    width: 100%;
}

Update:

, , scaleX width, , . .child .parent, div position: absolute. scaleX .parent, opacity .child ( , parent-child).
