"... allowing everyone access to what they need from our 网站 in a format that works 为他们."

To accomplish this, we are implementing programs to help us meet guidelines set forth by Section 504 of the Rehabilitation Act of 1973 and the Americans with Disabilities 1990年法案. These guidelines outline a number of areas focused on web design and 内容，以下是目前正在解决的一些问题:

• provide content that can be accessed using assistive technology devices
• provide consistency in content organization which sets a pattern for navigation throughout 这个网站 
• provide appropriate help text for images enabling message delivery even when the image 无法显示或查看
• provide appropriate contrast in colors used within the message so that those who suffer from color blindness will be able to discern the intended message
• provide navigation that works on a variety of devices and platforms from desktop computers 手机和平板电脑
