The Definite theme gives you a wide (full-width) layout for your page content. You also get a setting to adjust the width if you decide to make it smaller. You can go as low as 1024 pixels or as high as 1200 pixels.
NOTE: If you decide to set a page background colour with the content area background colour options, this width adjustment will help give the appearance of a boxed layout.
- Go to Appearance > Theme Options > Basic Settings.
- Find the Content Width setting and move the slider to the width you want. You can see the live preview as you move the slider.
- Click the Publish button.
