Wrap text around photo, remove post excerpts

Hi!

I’m having a seriously hard time with this theme. I don’t know if my theme is an old theme, but I’m having a lot of trouble. My website is https://www.thenaturalhairblog.com

First, no matter how many things I try I can’t get text to wrap right around my photos or the padding to increase. I’ve used this and it hasn’t worked.

img.alignright { float: right; margin: 10px 5px 10px 8px; }
img.alignleft { float: left; margin: 10px 5px 10px 8px; }
img.aligncenter { display: block; margin-left: auto; margin-right: auto; }
.alignright { float: right; }
.alignleft { float: left; }
.aligncenter { display: block; margin-left: auto; margin-right: auto; }

Right now it appears that the text is wrapping, but it’s because I’ve clumped the paragraphs together. If I don’t clump them together a huge space will occur.

Next, I want to get rid of the post excerpt, author and date at the bottom of each blog category. I tried looking replacing the_excerpt with the_content and it didn’t work.

Please if you can help me I would really appreciate it.
