PDF form with conditional font color/format change

[drewyoon]

Hello, I'm trying to make an interactive/fillable PDF form. 

I'm new to this, so I might need some walking through..

1) If the sentence starts with Perfect. (in this case, the only word in the field will be Perfect.)

for the font color to change to blue, (normally red as default).

> Will the font change back to red if Perfect. is deleted?Because I only need it to be blue in this one case.

2) If the sentence starts with Suggested Answer : 

to have those first two words and the colon to be italicized, but not the rest of the text.

I was told that these require some complicated solutions. But I'd appreciate any help I can get!

Thank you.

2) use span objects for this. Samples are in the Acrobat Javascript Reference.

Yes, this is pretty complicated. But detailed study of span objects will help you if you are already a programmer. If not, it may be too ambitious a project.
