There is nothing that screams amateur like a website with a mishmash of fonts and styles. Sometimes people copy and paste posts from a document they’ve already created in Word. Unfortunately that can also copy the Word styles and fonts into the WordPress document. In order to keep your styles and fonts consistent in your WordPress posts, click the “paste as plain text” icon in the toolbar. It will delete all the Word code and paste nice clean text into your post that will use the styles in your WordPress theme and keep your blog looking well-designed and professional.
