Blog Post, custom code, want centered

I already have some custom code on my blog to make it narrower

.BlogList .sqs-col-12 .sqs-block {
  width: 60% !important;
  max-width: 60% !important;
}

But I just want it centred on the page. Which seems like it should be pretty simple code. 

Help! Thanks in advance

xo,

@becciames You can add this code snippet to center the content:

.BlogList .sqs-col-12 .sqs-block {
	margin: 0 auto !important;
}

But then it becomes full width again. How do I keep it at 60% width?

@becciames Don't remove your previous code. Just add the code I wrote in my previous post. 

Oh, I didn't. This is what it looks like.

@becciames You added it wrong. It's missing a "}" in the code. Remove everything and add this code:

.BlogList .sqs-col-12 .sqs-block {
	width: 60% !important;
	max-width: 60% !important;
	margin: 0 auto !important;
}

You are AMAZING!!! Life saver! Thank you so much!!!
