Changing the sizing of my image, causes it go go off-center

Here is the code that I've been working on:

https://w.trhou.se/hflno29v2k

I've included an image of Arnold and since the image is so huge I want to downscale it. But whenever I change the width (under the style.css) for some reason the image gets thrown towards the left.

In order to change the sizing, I've only been adjusting the sizing below from the .logo (instead of a width of 100% I changed it to 60%). Let me know if this makes any sense and if you can point me in the right direction. Thanks!

.logo{ width: 60%; }

You have put an image (an inline element) inside .logo (a block element). By default the image is going to stick to the left of its container, so if you set the image width to be smaller then it will appear to be thrown to the left. To make image center inside the container, you have a few ways:

Method 1: Leave the container unchanged, but change image to a block element.

.logo img {
  width: 50%; /* Anything smaller than the container width will work. */
  display: block;
  margin: auto;
}

Method 2: Change the container alignment setting, and leave the image as an inline element.

.logo {
  text-align: center;
}
.logo img {
  width: 50%; /* Anything smaller than the container width will work. */
}

Method 3: Alternatively, if you want to control the image by setting the width of .logo, then you need to make sure the image changes its size relative to the container, namely setting image width to be 100%.

.logo {
  width: 60%;
  margin-left: auto;
  margin-right: auto;
}
.logo img {
  width: 100%;
}

:point_right: You need to adjust the width of the image, not the image's container.

While your image remained centered inside the container, by reducing the width of the container, it caused everything in it to shift left. Also, you may have noticed that your image was not getting any smaller.

So, instead of this:

.logo{
  width: 60%;
}

.logo img {
  margin: 0 auto;
  display: block;
}

try this:

.logo img {
  width: 60%;
  margin: 0 auto;
  display: block;
}
