justified text

You can horizontally align text in a 'Basic' page by using the 'text-align' CSS property.
On your 'Basic' page, click the 'Source' button in the toolbar of the text editor and enter code such as:

<p style="text-align: left;">Text aligned left.</p>
<p style="text-align: right;">Text aligned right.</p>

This will justify the text to the margins of your page's content section.
