You can specify the <accessibility-profile> element in the trinidad-config.xml file. Valid options are high-contrast, large-fonts, or both. The acceptable values for <accessibility-profile> are as follows:
ADF Faces can generate high-contrast–friendly visual content. The ADF Faces high-contrast mode makes ADF Faces applications compatible with operating systems or browsers that have high-contrast features enabled. For example, ADF Faces changes its use of background images and background colors in high-contrast mode to prevent the loss of visual information.
The ADF Faces high-contrast mode is more beneficial if used in conjunction with your browser's or operating system's high-contrast mode. Also, some users might find it beneficial to use large-fonts mode along with high-contrast mode.
<accessibility-profile>high-contrast</accessibility-profile>
ADF Faces can generate browser zoom–friendly content. In default mode, most text and many containers have a fixed font size to provide a consistent and defined look. In large-fonts mode, text and containers have a scalable font size, which enables ADF Faces to be compatible with browsers that are set to larger font sizes and to work with browser zoom capabilities.
Some users might find it beneficial to use high-contrast mode along with large-fonts mode. However, if you are not using a large-font mode or browser-zoom capabilities, disable large-fonts mode.
<accessibility-profile>large-fonts</accessibility-profile>
If you require both the high-contrast and large-fonts options, include the following entry in the trinidad-config.xml file:
<accessibility-profile>high-contrast large-fonts</accessibility-profile>
If application-level access requires all the options to be set, include the following entry in the trinidad-config.xml file:
<accessibility-mode>screenReader</accessibility-mode> <accessibility-profile>high-contrast large-fonts</accessibility-profile>
