Now for a new theme [a premium theme]: Newsy @ 01/2012  v1.3-wpcom. Following are 11 areas where I have made changes to this theme:

h1,section { /* tightened article title spacing */
line-height:27px;
}

div.entry-meta { /* reduced the spacing from categories & tags from 19px */
margin-bottom:5px;
}

#site-title a { /* set the header title from black to white */
color:#fff;
}

#site-title { /* remove the crowding of text below the title  */
margin-bottom:4px;
}

.widget-title { /* center aligns sidebar headings */
text-align:center;
}

tbody tr:nth-child(even) td { /* set alternate table row bg color from gray to white [so they are not visible] */
background:#ffffff;
}

#main { /* reduced white space at the top of the page from 38px  */
padding-top:12px;
}

p { /* changed line-height by 2px from 19px; and, set bottom margin to reduce space before gray line from 19px */
line-height: 18px;
margin:0 0 10px;
}

.hentry {  /* reduced white space at the bottom of each article from 38px  */
margin-bottom:1px;
}

#colophon .widget { /*reduced widget & supplemental menu spacing from 38px */
margin:0 0 1px;
}

.gallery-item { /*set the minimum white space beneath a gallery from 24px */
margin
margin-bottom:0;
}

It is okay to copy CSS code from here and use or modify as you choose. If you do, please leave a comment that you are doing so. I appreciate it and thanks! –jim
