Sidebar Size Issue

Your CSS includes:

.sidebar .widget {
	border-top: 1px solid #eee;
	padding: 100px;
}

Change that to

.sidebar .widget {
	border-top: 1px solid #eee;
	padding: 1em;
}

To add CSS:

• If you are using WordPress 4.7 or later, use the “Additional CSS” option in the customizer.
• If your theme has a custom CSS option, use that to add the CSS shown above.
• If not, install the plugin Simple Custom CSS.

Learn to use the Chrome Developer Tools to help you see and test changes to your CSS.

You have this in your style sheet:

.sidebar .widget {
    border-top: 1px solid #eee;
    padding: 100px;
}

If you have edited theme files, you’ll need to undo those changes.

Thank you so much! Resolved.
