Basic HTML provides the ability to add some basic text formatting to your document. When enabled, it adds the Bold, Italic, Styles, Horizontal Rule Line and Linking toolbar buttons that apply these styles.
...
If you want to remove basic styles from your document, you can also use the Remove Formatbutton to remove these styles. You can also insert and remove a Numbered List or a Bulleted List as well in this mode. Adding Files, Images, or Block Quotes are also available to you. With the Source button, you can quickly switch between Basic HTML mode to Source code mode, where you can hardcode your HTML tags manually.
You can align images, videos, blockquotes and so on to the left, right or center. Examples:
...
Align an image to the left: <img src="" data-align="left" />
...
Align an image to the center: <img src="" data-align="center" />
...
Align an image to the right: <img src="" data-align="right" />
...
