During the transition from an ASP .NET user control-based page with a header, footer, and menu to a Master Page utilizing the same HTML structure, is it common for CSS or javascript functionalities to experience slight alterations?
Specifically, after migrating, the submenu bar text may appear condensed (indicative of a potential CSS issue), and the graphics on the line above it may exhibit incorrect z-ordering. (The menu functionality relies on javascript.)
(I attempted to include images here but was unable to do so.)
Furthermore, since the site is quite extensive, we have not received approval to revamp the entire menu. This migration process is strictly forward-moving. (Anticipating the inevitable question about this restriction.)
In light of maintaining the existing scope, what aspects should I investigate?
Appreciate any insights!
