Center an image horizontally using CSS

I am trying to center a image horizontally using css.

I am displaying my image on the screen with the following HTML code:

<div id="loading" class="loading-invisible">  
    <img class="loading" src="logo.png">
</div>

I am croping my image as I only want to display some of the image and I am using the following css:

img.loading 
{
position:absolute;
clip:rect(0px,681px,75px,180px);
}

however I can't work out how to center the image once it has been croped.

Anyone able to help ?

Try this for your CSS:

.center img {        
  display:block;
  margin-left:auto;
  margin-right:auto;
}

and then add to your image to center it:

class="center"

use position absolute and margin like this

img.loading{
  position: absolute;
  left: 50%;
  margin-left: -(half ot the image width)px
}

You can use different method:

Method 1:

Its a simple method, use "text-align: center;" for your parent div.

#loading {
  text-align: center;
}

<div id="loading" class="loading-invisible">  
    <img class="loading" src="https://dummyimage.com/200x100/000/fff.png&text=Logo">
</div>

FIDDLE

Method 2:

Please check the code:

#loading img {
  margin: 0 auto;
  display: block;
  float: none; 
  /*width: 200px; if its a large image, it need a width for align center*/
}

<div id="loading" class="loading-invisible">  
    <img class="loading" src="https://dummyimage.com/200x100/000/fff.png&text=Logo">
</div>

FIDDLE

Method 3:

Using "display: flex;"

#loading {
  display: flex;
  align-items: center;
  justify-content: center;
}

<div id="loading" class="loading-invisible">  
    <img class="loading" src="https://dummyimage.com/200x100/000/fff.png&text=Logo">
</div>

FIDDLE

Method 4:

You can use "position: absolute;",

#loading {
        position: relative;
        }
#loading img{
        position: absolute;
        top: 0;
        left: 50%;
        margin-right: -50%;
        transform: translate(-50%, 0%);
        -ms-transform: translate(-50%, 0%);
        -webkit-transform: translate(-50%, 0%);
        -moz-transform: translate(-50%, 0%);
        -o-transform: translate(-50%, 0%);
}

<div id="loading" class="loading-invisible">  
    <img class="loading" src="https://dummyimage.com/200x100/000/fff.png&text=Logo">
</div>

Use margin

margin-left:auto;
margin-right:auto;
