Use of appropriate media for different children. Considering the previous section, it results quite intuitive how and when to use media like text, graphic, video and speech to better meet the children needs. Background graphics, text colors and colorful images are often used in the design of Web pages.

Control is critical.
Control may be related with input and output devices, information and or navigation. Control on information structure and nature has been already presented. By a device perspective, an interesting point to be considered is that normally, children are more initially motivated using no conventional devices like 3D joystick but has more control using standard keyboard. To reach the broadest number of children with disabilities the tasks associated in controlling Web navigation, in general, need to have multiple selection techniques, including both mouse pointing and keyboard equivalents using sequential and direct selection and possibly adding meaning sound to links. Moreover, navigation includes the feedback of the effect of each command.
