The State of California (the State) websites strive to be a model of accessibility that meets the access needs of any site visitor. The State has implemented the strict guidelines set forth by the World Wide Web Consortium (W3C) and the US Department of Justice (DOJ). The websites meets most of the W3C Web Content Accessibility Guidelines 2.0 (WCAG 2.0 – AA Guidelines and Success Criteria) and all of the Section 508, Technical Standards (Subpart B).

One of the pillars of accessible web design is using defaults, and certain design elements that can be adjusted by the end user. This kind of design permits visitors to adjust font size, contrast, and customize other elements to meet their particular viewing needs. Information on some of our special access features, and how to work with custom settings, are described below.

1. Contrast

2. Fonts

3. Keyboard Shortcuts for:

1. Internet Explorer

2. Firefox

3. Chrome

4. Safari


High contrast is necessary for many users. The State’s websites uses style sheets and some of the best contrast combinations, black on white, white on dark green, or blue on white. However, some users can see better using high contrast reverse types, such as white on black, or different colors. Below are guidelines for some common web browsers on how the user can customize their own web browser to better view all web pages.

Internet Explorer

Select the “Tools” menu. Select “Internet Options”. Under the “General” tab, select “Accessibility”. Place a check mark in the box to “Ignore colors specified on Web pages” and select the “OK” box. This will return you to the “General” tab. Select the “Colors” box and un-check the “use Windows colors” box. Use the “Text”, “Background”, “Unvisited Links”, and “Visited Links” boxes to select the colors desired (example: white text and black background). Select the “OK” box and then the “OK” box on the “General” tab and the colors should change on the browser.


Select the “Tools” menu. Select “Options”. Select the “Content” tab. Select “Colors”. Select colors desired for “Text”, “Background”, “Unvisited Links”, and “Visited Links” (example: white text and black background) and uncheck “Allow pages to choose their own colors, instead of my selections above”. Select the “OK” box, and then the “OK” box again. The colors should change on the browser.

Google Chrome

High Contrast and Custom Color Support

There are a number of steps you can take to configure Chrome to run with custom contrast and colors:

  1. Install a Chrome Extension which allows you to specify your own custom color combinations, for instance the Change Colors extension.
    1. Quick page action to apply/remove styling overrides on a per page, per domain or global basis (overriding Web page colors)
    2. Optional background, text, links and visited links color configuration
    3. Option for showing/hiding images
    4. Option for showing/hiding Flash objects
  2. Use a Chrome Theme for some control of the color scheme of the Chrome user interface. As an example, the BitNova Dark theme offers white text on a black background. The Chrome Extensions Gallery offers many other themes, with a variety of color combinations.


Fonts and colors for unstyled webpages

Sometimes, webpages do not have a specified style for fonts, background color, or link colors. We have selected some default fonts and colors for you, but you may prefer to choose your own. To do this, select Settings > Preferences > webpages and select your preferred fonts, background color, or colors for normal and visited links. You can also enable or disable an underline for links.


A theme is a color scheme of the buttons and background images in the browser. You can apply a theme to Opera to entirely change the way Opera looks. To try a new theme:

  1. Go to Opera add-ons. (Search for Contrast theme) Alternatively, select Appearance > Themes.
  2. Select “Find more themes. The available themes display.
  3. Choose one you like and select the “Add to Opera” button. The theme is applied so you can see if you like it.
  4. In the bar that displays at the top of the window, select either “Done X” to confirm the theme change and keep it, or “Undo” and everything will be back to the way it was. If you don’t make a decision after a short while, the theme is applied automatically.

Manage themes

To see a list of all of the themes you have installed, select Appearance > Themes. You can delete or switch themes, or add new ones by selecting the “Find More Themes” button.

Not all webpages clearly specify styling for all page elements. Use this preference setting to choose which colors to use, and whether links should be underlined in such cases.

International fonts

If international characters appear incorrectly on a webpage, try changing the font used for the respective language.

Note: You may have to install fonts that are missing on your system. 

Webpage fonts

Not all webpages clearly specify styling for all page elements. To choose which fonts to use in these cases, go to Settings > Preferences > Webpages.


Zoom in on webpages

You can make text and images larger so they’re easier to view.

  • Make the webpage content larger: Choose View > Zoom In, press the Command Key (⌘) – Plus Sign (+), or pinch open on your trackpad. To make only text larger, choose View > Zoom Text Only before you zoom in.

Another way to change the font size is with Cascading Style Sheets (CSS). However, this may require a programming class in CSS for the more intrepid individual.
