Can I change the font size?

When reading the ePaper in your browser, the entire page can be enlarged by using the slide tool located in the top left corner.  Dragging the dot left or right will shrink or increase the page size and font.  Clicking the +/- will also cause the same effect.

While in the browser, if you are reading an article in article view, the "A+" and "A-" will increase or shrink the font size.

When reading the ePaper within the iOS or Android app, tap on an article to open up the desired article, then tap on the "A" in the top menu.

This will open up a text sizing menu.  Dragging to the left or right will shrink or increase the text size.  Don't forget to tap Save before exiting the sizing menu.
