I just notice that chrome also has an accessibility setting. On the one hand, it connects with computer system preference, making subtitles and texts having different sizes, colours, and backgrounds. On the other hand, users can add more accessibility features such as a colour enhancer, high contrast, long description in the context menu, notebook web clipper, etc.
According to those feedbacks, these tools are really helped a lot, making those persons with disability can easily use digital media.
