Align images - top and side by side

Image CSS

What CSS call can I use in the child theme to have all images align next to each other automatically, then wrap to the next line as needed. I can set a margin and padding, but I can't get them to align across the top in the edit window.

I have to manually click on each image and do a left justify just to get it as you in the attachment. It seems to display well enough.

I just felt like I'm missing something in my not-so-knowledgeable CSS.

This is what I have in the child theme

img {
     margin: 5px;
     padding: 10px;
	 float: left;
	 veritcal-align:top;
     
}
