如何垂直和水平中心光滑滑块？

Question

I need my slick slider carousel to be completely centered in whatever browser someone is viewing it in. In other words, whether your viewing it in desktop chrome or an iPhone X Max the slider is positioned in the middle of the viewport. the slider is stuck to the top of the page.

I've tried every solution i could find but whatever i try the carosuel remains stuck to the top of the page.

this is the first method i tried https://github.com/kenwheeler/slick/issues/281
I tried to fiddle with what i found in both slick.css and slick-theme.css and still couldnt figure it out.

.slick-slide.c {
    display: inline-block;
    vertical-align: middle;
    float:none;
}

 My current style.css 

#wrapper{
  width: 100%;
  margin: auto;
  height: 100%;
  background: grey;
  }

html, body {
  height: 100%;
  margin: 0
}
body.Site{
  text-align: center;
  width: 100%;
  outline: 0;
  min-height: 100%;
  background: blue;

}
main.Site-content{


}
footer {

  height: 120px;
  background: red;

}

.barcode{
font-family: 'Libre Barcode 39', cursive;
font-size: 2vw;
}



.slider {
  display: block;
  margin: 0 auto;
  text-align: center;
  font-size: 17px;
  background: green;

}

.player {
  width: 80%;
  text-align: center;
  background: purple;
  outline: 0;
}


I expect my slider to remain centered vertically and horizontally within its viewport.

Here is the code you can use to center your slider horizontally and vertically. As there are some issues in adding external libraries in the code snippet, I have created a codepen for you. You can refer to this link :

 $('.slider-nav').slick({ slidesToShow: 3, slidesToScroll: 1, asNavFor: '.slider-for', dots: true, focusOnSelect: true }); 

 body{ background:#ccc; } .main { font-family:Arial; width:500px; display:block; margin:0 auto; position: absolute; top: 50%; left: 50%; transform: translate(-50%, -50%); } h3 { background: #fff; color: #3498db; font-size: 36px; line-height: 100px; margin: 10px; padding: 2%; position: relative; text-align: center; }

EDIT NOTE: Please check the codepen link instead of snippet result for the final result.
