MHT Format and Accessibility with Screenreaders (JAWS) RRS feed

  • Question

  • Does anyone know if there is any difference when using MHT format over word with respect to accessibility? Is there anywhere known to find more information?

    We are trying to meet Ontario legislative requirements, but the file format doesn't have much support on this topic.

  • Hi,

    mht files use either the mht or file protocol with a Mark of the web at the top of the modified html file. All internet hyperlinks in the mht file are preserved.. and x-ua tags honored..By default mht files are mapped to the Internet zone where ActiveX filtering may be active... I would think that JAWS is implemented in IE as an ActiveX control. You may have to turn off ActiveX filtering or enable the JAWS addon in the Addons Manager (Tools>Manage Addons>Show all addons)

    Your JAWS installation may be using Landmark Roles to build the Accessibility tree it uses, that may be absent from the saved mht file or absent from the website where you have saved the file or IE11 is using an Emulation mode of a previous version.

    I have had no problems at all with Wikipedia content saved as mht using the MS Narrator and IE11. (It helps us answer your questions if you can include links to problem websites with your questions).

    You can still use the IE11 f12 developer tool to inspect mht saved content, to determine the landmark elements and the Emulation mode that has been applied. (see the Emulation tab of the f12 dev tool). All emulation modes of IE do not support the ::visited pseudo style (except for color changes).

    The JAWS support site or stackoverflow.com is a good place to ask IE or JAWS or other developer questions.
