Web Browsers’ Zoom Comparsion

Name	Description	Work on text?	Work on gaphics?	Usability issue	Personal preference
Text-zoom	Change and override the displayed text size	Yes but not always(due to CSS issues)	No	May break web pages layout since the changes in text size may not be expected by the web designer and any layout related config like CSS may not be able to catch the changes.	Rarely used
Page-zoom	Adjust the page by emulating a larger/smaller screen size	Yes	Yes	When the zoomed-page exceed the window size, user may need to scroll heavily both vertically and horizontally. Centralized page will keep in center in the zoomed screen, however eventually user won't be able to see that effect because the actually screen size does not match the zoomed screen size, and the scroll bars won't auto-scroll to center for you. As a result an orginally centered object will now shift a bit to top-left corner.	Not interested, hate horizontal scroll
Screen-zoom	Adjust all objects' sizes while keeping the same screen size, just like zooming all objects except the stage which holds them	Yes	Yes	In most cases content will squeeze to fit the screen horizontally, however when zoomed too much, that reach the minimum width limit, the page will start to expand outside the screen. This method will affect but not breaking the design, in most cases. In this case designer can consider having a a little more flexible design just like dealing with different screen resolution, much less input but great outcome.	Best
