Detail Forms: Add smaller instructions text under the Title

for the detail forms (Read only) Can you allow the "title" to have smaller type "instructions" like on add and edit forms?

You'll have to do that with CSS...

/* FOR ALL VIEWS */
.kn-subtitle {
font-size: 14px;
}
/* FOR ONLY ONE VIEW */
#view_XXX .kn-subtitle {
font-size: 14px;
}
*** Replace XXX with the number of the view you want to apply the change to ***
