How to make featured images show up on the left side from content in the WordPress blog page

It’s actually pretty simple, you just need to add custom CSS for featured images. Trust me, it’s not as scary as it sounds. This piece of code will do the thing:

[class="attachment-full  wp-post-image"] {
	height:50%;
	max-width:50%;
	float: left;
	margin-right:20px;
	padding-right: 20px;
}

Of course in your case the class might be different, depending on your theme. So the best way to figure out is to right-click on the image and inspect element:

So we scale it down with “height” and “max-width” and then shifting it to the left with “float: left”. Now all we have to do is make sure there’s a margin between the image and the text, so we apply the “margin-left” and “padding-right” code (some themes react on margin, some on padding, so it’s better to use both just in case)
