Chrome : Text blurry when skew back : skew(-10deg) -> skew(10deg)

问题

I just want to skew the parent and skew it back on the child.

Example : HTML

<div class="parent"> <!-- skew(-10deg) -->
    <div class="child">Hello</div> <!-- skew(10deg) (skew back) -->
</div>

Example : CSS

.parent {
    transform: skew(-10deg);
}
.child {
    transform: skew(10deg);
}

Text inside seems ok with Firefox, Safari. But not Chrome and Opera its a bit blurry

I have to use -webkit-backface-visibility: hidden; for reduce box pixelated in Chrome

Firefox :

Chrome :

Firefox vs Chrome :

or zoomed by Photoshop

Live example : http://jsfiddle.net/1tpj1kka/

Any idea ?

NOTE !!! : web-tiki's answer is an another way solution to prevent the problem. But if any answered a real solution to resolved this skew back problem (real fix), I will accept the answer.

The "blurry text" after 2d or 3d transforms with webkit browsers has been discused many times. But in your case, you can apply the transform only on a pseudo element so that your text isn't affected by the skew property.

It will also alow you to use only one tag in your markup :

@import url(https://fonts.googleapis.com/css?family=Oswald);
body{color:#fff;font-weight: bold;font-size:50px;font-family:'Oswald',sans-serif;}

.parent {
    width: 300px;
    overflow: hidden;
    padding-left: 5%;
    position:relative;
}

.parent::before {
    content :'';
    position:absolute;
    top:0;left:0;
    width:100%; height:100%;
    background: rgba(90,190,230,0.9);
    transform-origin:0 0;
    transform:skew(-10deg);
    z-index:-1;
}

<div class="parent">
    Hello
</div>

Adding the 'translateZ(0)' before transformations like below forces the gpu to re-render the text and removes blurry-ness on Chrome.

This:

transform:  translateZ(0) skew(-10deg);

Not This:

transform: skew(-10deg);

You can try the text-rendering: geometricPrecision CSS property. This will force your text to not be anti-aliased, thus making the blurriness less important.

inp.onchange = function(){
   document.querySelector('.child').classList.toggle('geo');
  }

@import url(https://fonts.googleapis.com/css?family=Oswald);body{color:#fff;font-weight:bold;font-size:50px;font-family:'Oswald',sans-serif;}

.geo{
    text-rendering: geometricPrecision;
  }
.parent {

  transform: skew(-10deg);
  -webkit-backface-visibility: hidden;  
  width:300px;padding-left:15%;margin-left:-15%;overflow:hidden;
}

.child {
  transform: skew(10deg);  
  width:300px;background: rgba(90, 190, 230, 0.9);padding-left: 5%;padding-right: 15%;
}

<div class="parent"> <!-- skew(-10deg) -->
    <div class="child geo">Hello</div> <!-- skew(10deg) (skew back) -->
</div>
<input type="checkbox" id="inp" checked="true"/> geometricPrecision
