Basic CSS styles not applying - css

Question

I cannot figure out how to get some basic CSS styles to apply to my blog. I'm trying to customize my blog summary page. I want the "read more" button centered and for the picture to show correctly. For some reason the picture keeps moving and it cuts it half off. I've tried multiple things to different classes and nothing works. It was originally on the left with the text to the right of the thumbnail and I'm moving the picture above the text if that means anything.
I've tried text align center for the button in multiple divs and it doesn't budge. Can anyone help? I can only adjust CSS not HTML on my Squarespace site, and the limited styles they give you doesn't allow me to adjust any of this. I'm not a coder, I just kinda understand it enough, so any help is appreciated.

Here is custom CSS I added to make the button a circle, but can't get it to center:
text-align: center;
display: table;
width: 100px;
border-radius: 30px;
padding: 12px !important;
background-color: #f0ede9;
margin: auto;
}
.view-list article .excerpt-thumb {
width: 100%;
position: inherit;
}
.view-list article .excerpt-thumb .intrinsic .content {
position: inherit;
padding-bottom: 0px;
}
.intrinsic {
padding: 0px !important;
}
.entry-title {
text-align: center;
}
.article-dateline {
text-align: center;
}
article .post span.inline-action {
display: inline-block;
text-align: center;
}
.article-meta {
display: none;
}

Answer 1

I'd recommend centering the "READ MORE" button using the following CSS, inserted via the CSS Editor:
article .post span.inline-action {
display: inline-block;
text-align: center;
}
The "cut off" image problem, on the other hand, should not be corrected with CSS because it is an issue with Squarespace's ImageLoader function. To correct it, add the following via global Footer code injection. If code injection is not available to you, insert the code via a Markdown block in the footer of your website.
<script>
// Fix Squarespace ImageLoader Bug.
function fixImages() {
var images = document.querySelectorAll('img[data-src]');
var i = images.length;
while (i--) {
ImageLoader.load(images[i], {load: true});
}
}
fixImages();
window.Squarespace.onInitialize(Y, function() {
fixImages();
});
</script>

Your images are cut off because you have a top: value that's currently set to -300px. I can't tell where it's being affected just by looking at this, but somewhere in your styling you have the child img of your excerpt-image getting a top value being set.
To center your 'read more' link: .inline-read-more { margin: auto; }
