#theme1q

if you find 

#wrapper #content .post .copy {...font-size: 10px;...}

and change the font-size, it'll change the size of some of the text in the posts, but not all of it, and the sidebar will also stay the same

to change the font size of the sidebar, find

#wrapper #sidebar {...}for theme 1 OR 

#wrapper #sidebar #sidedesc {...} 

for theme 2

heeere u go

it looks like the picture itself is too small

if you want the picture to stretch to fit the posts no matter what the size is try finding

#wrapper #content .post img {

(blahblahblah)

}

delete the stuff that's there and just put in width: 500px; (assuming you have 500px posts selected)

#wrapper #content .post img {

width: 500px;

}

im not sure which theme this is for but this will work for either of them i think

in the html, find:

{block:HasTags}

{block:Tags}#{Tag} {/block:Tags}

{/block:HasTags}

around that, put {block:PermalinkPage} and {/block:PermalinkPage}

so it’ll look like:

 {block:PermalinkPage}{block:HasTags}

{block:Tags}#{Tag} {/block:Tags}

{/block:HasTags}{/block:PermalinkPage}

that should make it so the tags only show up on post pages

also, right above that, put those tags around 

{block:HasTags}display:block;{/block:HasTags}

otherwise there will be a random block sitting on the bottom of posts

so that whole part should look like this

{block:PermalinkPage}{block:HasTags}display:block;{/block:HasTags}{/block:PermalinkPage} {block:ContentSource}display:block;{/block:ContentSource}">

{block:PermalinkPage}{block:HasTags}

{block:Tags}#{Tag} {/block:Tags}

you're supposed to position it with these

in the code, find:

#wrapper #content .post .album_art { text-align: center;}

and right below that, put: 

here
