change the width of the content

anyone can help me?

You can try adding 2 sidebars to whatever page(s) are too wide. It basically centers everything.

Thanks ibogo, what happens is that I want to keep a clean look, to make it easier to read without distractions.

Remove all features in the sidebars (under widgets – remove everything). Now sidebars are empty and everything will be centered.

To add sidebars click “edit page” and on the right side you will see an option for sidebars. Click that and select “2 sidebars right and left”. Everything on your page will be centered.
