Theme #13: Beat
Features:
Go into the custom HTML and do ctrl f to find #bonnie{width:500px; padding-top:10px; padding-bottom:10px;}
Replace this code with #bonnie{border:1px solid #fff; margin-bottom:14px; width:500px; padding-top:10px; padding-bottom:10px;}
Then change the properties of border: to whatever you like (bigger, smaller, dashed, different color, etc).

Theme #12: Xeno
Features:
Oh? Is the button not appearing, or is it not clickable, or what? If you’re using it on your blog you can come off anon and I can look at it. If you want infinite scroll regardless, http://codysherman.com/tools/infinite-scrolling is the page for it. (I would’ve linked it but Tumblr’s stupid post editor doesn’t ever work right.) Follow the instructions there, and search for div class=”paginationel” in the code, and remove what’s between the < div class > and the < /div >. I can’t guarantee it will work though.
Thank you very much for letting me know! I encourage my followers to notify me when they see things like this. However, while I prefer credit on the page to be kept, credit in the source code was kept, so it is acceptable.

I’ve never really done any multi column work beyond experimenting but from what I know… it’s kind of complicated, I don’t know if my explanation will be enough so you might want to google “tumblr multi column tutorial” or something like that
To make it multi column you probably want to make the post size smaller. You have to find the part near the beginning where it says #stockett and #bonnie. bonnie is the width of the posts, so change width:500px to probably 250px but you can experiment with that. (it’ll look different than that because there are options for bigger posts. you can take out anything in curly brackets that looks like {block:If500pxPosts} or anything like that, just make it width:250px and don’t worry about that.) stockett is the width of the post area, so you make it way bigger than the post size. So like, if you wanted 2 columns you’d double whatever you put for bonnie, and then add probably 50px or so more to account for padding.
Also copy and paste #bonnie{float:left;} on a new line under that
I don’t know if that will work. If it does, it will look awkward because you need a special code to make them all fit together instead of lining up in rows. ettudis has a tutorial for how to install this code under their tutorial section. If you don’t want them to be staggered, put height:200px; or however long you want your posts to be in #bonnie as well.
I might make a multi column version of that theme, that’s a good idea! Sorry I couldn’t be of more help!
Ahhh thank you so much darling <3
