Correcting alternate text tags for images.
The purpose of alternate text: When an image can not be displayed in a web page, or to a person who has impaired vision alternate text provides information explaining the picture.

Correcting an image with AccRepair is fairly straight forward. If you have set the base path you will see the picture in the right window and the code in the left window. (If you have not set a base path, or if the image is not in your folder, the right window will be blank.)

1. Type the alternate text you wish associated with the particular picture displayed.
   
   Note: If you use the same picture more than once AccRepair will remember the alternate text you used the first time and automatically use that same text each time that particular graphic is used, saving you time. If you would rather not have this feature working uncheck the box marked "Update Library".
   
   Note: If you use blank images for formatting or spacing purposes you can use a blank space (typing a single spacebar stroke) as the alternate text.

Correcting alternate text errors for image maps and area elements

2. If you are using an image map within your webpage, it is important that you include an alt tag for any links using the image map.

3. When you have completed entering alt tags for your images AccRepair will display a listing of all the changes it has made to the file. Click "Next" if there are more errors to fix in this file, or "Finish" to go to the next file.

Input fields allow users to enter information for some sort of processing.  Depending on the layout of a webpage it can be difficult to know what a particular field expects as information. Alternate text ensures that a user, especially one using assistive technology, understands what is expected.

1. AccVerify will inform you that there is an error with an alternate tag for an input field. Click Next to repair.
    

2. AccRepair will list the code associated with the error and provide a box for the alternate text. The alternate text should indicate what information is requested in the input field.
    

3. When you have finished correcting all of the input fields AccRepair will display a listing of all the changes made to the file. Click "Next" if there are more errors to fix with this file, or "Finish" to go to the next file.

Correcting errors in pages with frames

Purpose of <frames> tag: Frames are used to break a page up into logical units. Many people use frames to provide a navigation area that never changes and a main display area. Use of the <noframes> tag allows people that do not have frames enabled to see that the site is not empty. You can also use this area to provide a link to a noframe version of your site. Proper use of the title attribute allows users of assistive technology to navigate the site easier by identifying which frame they are in.

1. AccVerify will inform you of errors in the file. Click "Next" to repair them.

2. AccRepair will list the code and provide you an area to type in a message for the NOFRAMES section. This message will be displayed to any person that does not have frames enabled, or a browser unable to display them. Click Ok.

3. AccRepair will display a listing of the changes made to the file. Click "Next" if there are more errors to fix with this file, or "Finish" to go to the next file.

Adding a title to a frame

1. AccRepair will display the code associated with the frame tag and provide you a place to type in a Title. This title is especially useful for users of assistive technologies. You should provide a name that is meaningful such as Navigation Bar or Main Display.

2. AccRepair will display a listing of the changes made to the file. Click "Next" if there are more errors to fix with this file, or "Finish" to go to the next file.

Blinking or marquee text is not allowed
Text that blinks or scrolls across the screen can cause seizures and is not allowed. Any text placed within a <blink> tag or a <marquee> tag must have the tag removed.

The blink or marquee tag must be removed from the code by hand.

Correcting the noscript error

Scripts allow small program-like functions to operate on a webpage. They can add flare or functionality to a website. If someone does not have scripts enabled they will miss out on any information that may be provided through a script without ever knowing. By providing the <noscript> tag you inform the user that there is something they are not receiving.

1. AccVerify will inform you of a missing noscript tag and ask if you wish to run the AccRepair utility. If you wish to do so, click Yes.

2. In the edit box provided type a message that will be seen by viewers who do not have scripts enabled.

3. AccRepair will provide a list of the changes made to the file. Click "Next" if there are more errors to fix with this file, or "Finish" to go to the next file.
