The default text font size on a browser is usually set to 10-point type size. The web page itself doesn't decide what size of letters to print on your screen. This is up to you to decide with your browser. Therefore, if your browser is set to a larger type size, this can result in that text that is meant to be seen in a frame will not fit in the frame. And if the font size is too big, some lines or headers may wrap around onto a second line.
You can fix this by decrease or increase the font size that your browser uses to display text on your screen.
If the font size is set correctly, you will be able to view the Grip Story with no problem and all that is meant to be seen in a frame will be there.
