Fixed spacing

Nothing to see here.
Fixed iFrame width

I've added the iframe selector (under img selector). Fixes Instagram embeds for smaller screen sizes.
Fixed <title>

Before this bit of PHP <?php wp_title(''); ?> between the <title> tags would render in the title bar. <?php wp_title('|', true, 'right'); ?> fixes this issue.

Before:
'  Blog Post TitleWebsite Title'

After:
'Blog Post Title | Website Title'
