If ExtraView Corporation is hosting your installation, you do not have direct access to the file system of the server to configure, alter or use this feature without contacting ExtraView support.
Each user can select between one of three font sizes as a personal option. These are named small, medium and large. When the user selects one of these, ExtraView loads a corresponding cascading style sheet (CSS). The style sheets installed by ExtraView are within your web server environment, defaulting to the directory named IMG_HOME/stylesheets. This contains a number of sections with font sizes and other style parameters.
If you want to create your own version of the style sheets, it is typical that you want to do this in conjunction with creating your own image set for all buttons. It is recommended that you retain the same structure of the existing image sets and stylesheets by creating a new directory and subdirectory within locales/en_US/images and copy an existing image set into this directory. You use the IMG_HOME behavior setting to point to this new directory, and then make all your changes within there. In this way future upgrades of ExtraView will not write over your files, although you may need to extend these files if new entries, images or stylesheet settings are part of the upgrade. Note that if you are using or creating localized versions of the image sets, you will need also to place the stylesheets in other locale directories. Your stylesheets/ directory must contain the following files:
| File | Purpose |
| small.css | The main stylesheet when the user selects the small text personal option |
| medium.css | The main stylesheet when the user selects the medium text personal option |
| large.css | The main stylesheet when the user selects the large text personal option |
| dnd.css | The style used to control the presentation of drag and drop objects |
| menustyle.css | The style of the menu used at the top of most screens |
| popupwindow.css | This style us used for window popups that are generated from within the browser, as opposed to being generated from the server |
| popupwindowsafari.css | This is similar to popupwindow.css, but is only used for the Apple Safari browser |
| tooltip.css | The style of popul tooltips that apper on many screens |
Typically you will not alter any of the existing styles. If you do so, then whatever changes you apply will need to be reapplied when you update your site.
Also, you must be careful in altering the existing styles as some of these are used for accurate positioning or sizing of objects on ExtraView screens. As a rule of thumb, you can alter colors safely, but you should be careful about altering all other style information.
The recommended strategy for altering styles is to add additional entries in the file stylesheets/user_stylesheets/user_Stylesheet.css. You can override any of the built in styles or add your own styles within this file.
Consult a good HTML or Cascading Style Sheet manual for full details of options available to set up alternate styles.
