Microsoft Windows operating system and Mac OS X have built-in screen magnification feature. In GovHK, the hyperlinks are usually descriptive, providing a brief summary of the content to follow. Hyperlinks that use phrases such as 'click here' or 'here' describe nothing of the content that the link leads to. The wording of each link on GovHK has also been carefully chosen to aid screen reader users. This not only makes it easier for general users to spot which link they need, but also for screen readers to read out the underlying website address (URL) of the hyperlinks. Hyperlinks can be embedded in a paragraph, within bullet points or presented on separate lines after the related paragraphs. Special consideration has been given to the presentation of hyperlinks on GovHK to make them easily accessible by both users with normal vision and those using screen readers. In this way, users can still know what these graphical elements represent. Use of Alternate TextĪll graphical elements such as photos, logos and banners are supplemented by alternate text descriptions for screen readers. By introducing hidden texts, visually impaired users can more easily navigate the website and access the information they need. These hidden texts are not visible on screen, but can be read out by screen readers. To make such hyperlinks meaningful when they are read out, hidden texts are used throughout GovHK. Hyperlinks that are visible to people with normal vision may be confusing to screen reader users. In this way, users of screen readers do not need to hear repeated information. The hidden link allows screen reader users to skip over standard parts of the website that are basically the same for every page, such as the logo, search buttons and language option buttons. GovHK has built in a hidden link ”skip main content” right on top of every webpage. All pages on GovHK are designed with a consistent and logical document structure, which is extremely important in helping the visually impaired users navigate around the portal quickly. In technical terms, the content framework is the “document structure” of a webpage. In this regard, a clear presentation of content framework or headings to screen reader software is crucial. With the help of screen reader software, they first listen to the headings of a webpage and jump directly to the most interested section. People with visual impairment have a different need. People with normal vision can scan through a webpage before starting to read the details.
This will allow screen reader users to identify each page more easily. GovHK also uses standardised templates that ensure all pages have a consistent format, layout and use of headings. GovHK uses Cascading Style Sheets to separate the text content from the visual presentation and layout so that your screen reader can easily read out the content in a correct and easy-to-understand order.
