Problem in centering images

-1

I have some problems with centering my images. Basically I wanted to center my images in the center of my page. But if for example I go to another PC with another resolution my site gets all deformatado.

I wanted to know if anyone could help me.

css:

}
.imagens1{
    position: absolute; 
    top: 220px; 
    left:310px; 
}

.imagens2{
    position: absolute; 
    top: 220px; 
    left: 550px; 
}

.imagens3{
    position: absolute; 
    top: 220px; 
    left: 790px; 
}

.imagens4{
    position: absolute; 
    top: 220px; 
    left: 1030px; 
}

html:

<center>
    <div class="w3-content w3-row">
    <div class="w3-col s4 imagens1">
        <br>
        <img class="mySlides1 w3-animate-fading" src="1a.jpg" height="312" width="237">

One of the many ways you can center an image is to use margins and percentages that differ from pixels, not depending on screen resolution.

.img {
  margin-left: 35%;
}
<img src="data:image/jpeg;base64,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

To center the images Horizontally and Vertically you can do as in this example .

With transform: translate(-50%,-50%) will center both horizontally and vertically. The field left and top must be specified.

How do you know width and height this way works well
