perceptibility – presenting information in such a way that it is perceptible to the senses of people with disabilities,

functionality – designing the interface so that the user can easily navigate the site,

understandability – maximum simplification of the interface to make it understandable to users with special needs,

robustness – understood as a way of creating content that can be interpreted overseas chinese in worldwide database by programs supporting web browsing.

These four principles also contain a number of detailed guidelines that should be followed when creating new websites and mobile applications and modifying existing ones to make them accessible to people with disabilities.

Perceptibility – improving the comprehensibility of content and graphics
This principle introduces standards, among others, in relation to creating alternative texts for graphics placed on websites or adding transcripts to video and audio materials, as well as subtitles to films. It is also necessary to ensure that the font is of the appropriate colour. It must be clear on a white background, and to strengthen the message, the most important content should be distinguished by a different colour. A clear text layout can be achieved by introducing an appropriate text structure, as well as using, for example, numbered lists).
