Random Post Option:
- Thumbnail Dimensions: to change the size of the thumbnails in pixels, replace the 50px value.
- Summary length: you can control the length of the summary (in characters) by changing the 50 value from var randomposts_chars=110;
- Post info: if you want to show the post date and comment count, change 'no' from var randomposts_details='no'; to 'yes';
- Font Size for Posts Titles and Summary: to modify the font size for the post snippet, modify the 11px value and for the posts title, the 10px value;
Click on the Save button and View your blog. The sidebar will display a random posts widget on each of your blog pages.
