While the universal navigation bar at the bottom of each screen will be hand-written to tie in with the hand-drawn theme, the explanation and quotes on subsequent pages will be typed to allow for better legibility.
Depending on the website builder used, if your own fonts can be imported and remain the same no matter the device, then headings and emphasis will use DK Lemon Yellow Sun in bold, with a size of at least 35 pixels, while body text will be typed with Arial, between 16 and 20 pixels.

As Austin and Doust (2007) note, it is much harder maintaining design on the web, as different devices have different screen sizes and default fonts that may affect your design. It used to be that exciting fonts were preserved as images, but this then caused problems with legibility when zooming, and did not allow for vision impaired programs to recognise text, effectively isolating that audience from accessing content. Thus, will have to view the site from different operating systems and devices to see that this isn’t an issue.
