Hi Chelsie. You are brave!
The spacing between the widgets in the sidebar of your site looks like it’s set in /wp-content/themes/responsive/style.css on line 1442 using the following CSS:
margin: 0 0 20px;
The margin setting in CSS is a shortcut for specific margin settings. The first setting is the top margin, the second the right, and the third (the 20px) is the bottom. You can set the 20px to any setting you like.
The easiest way to change it is to log in to the administrative side (back end) of WordPress, then go Appearance -> Editor, then click on style.css in the right column. Scroll down until you find the section for the class “widget-wrapper,” which should look like this:
.widget-wrapper {
background-color: #F9F9F9;
border: 1px solid #D6D6D6;
border-radius: 6px 6px 6px 6px;
font-size: 13px;
margin: 0 0 20px;
padding: 15px;
}
(In CSS, anything with a period in front of it is a class.)
Make your changes there, then click “Update File.” Say you wanted to set the bottom margin to 5px. You would change it so it looks like this:
.widget-wrapper {
background-color: #F9F9F9;
border: 1px solid #D6D6D6;
border-radius: 6px 6px 6px 6px;
font-size: 13px;
margin: 0 0 5px;
padding: 15px;
}
You can experiment with various settings by refreshing (reloading) your site, going back and forth between the administrative side and your site, until you get the look you want.
You may also want to play with the “padding” setting in the same class to see what it does and adjust accordingly.
