All browsers have variations in how they implement HTML, CSS, and PHP standards. This site is coded to the World Wide Web Consortium (W3C) Web standards for HTML5+ instead of the ever changing browsers. These pages are designed with Cascading Style Sheets (CSS) level 2.1 and 3 without the use of tables for the page layout.
The selection of which browser to use may not be under your control. However, if you do have control over what browser you are using, W3C standards-compliant browsers are Chrome, Edge, Firefox, Opera, and Safari. Use the Can I Use tool to compare support for your code in different browsers.
The Web standards are developed and maintained by the World Wide Web Consortium (W3C). The standards ensure that the Web will work better for all users.

Some hypertext links may take you to Portable Document Format (PDF) files you can view in your Web browser. Your modern browser may no longer support a PDF helper application. The Acrobat/Acrobat Reader plug-in for web browsers relies on the cross-platform plug-in architecture NPAPI, which had been supported by all major web browsers for over a decade. The following browsers have dropped support for NPAPI, and therefore Acrobat/Acrobat Reader plug-in does not work on these browsers anymore to display the PDF.
For more information, see Change in support for Acrobat and Reader plug-ins in modern web browsers.
If you can't view the PDF files or you get an error message, download and install the latest version of the FREE Acrobat® Reader™ plug-in for your browser: https://get.adobe.com/reader/otherversions. Some PDF files are saved with accessibility and search capabilities for screen readers. Acrobat Pro DC can compare two versions of a PDF to review all differences, turn scanned documents into editable, searchable PDFs, redact to permanently remove sensitive information in PDFs, and validate and fix PDFs for ISO and accessibility standards
PDF file links are marked by a (.pdf) following the link and may also include the size of the PDF with the .pdf file extension at the end of the link (250 KB .pdf). PDF files are extremely compact, platform-independent, and easy to create. They offer design control, print-ready documents, and an endless array of authoring applications. PDF is an extension of the Encapsulated PostScript format that allows hypertext linking. Some PDF files may contain hypertext links that take you to another location in the PDF file or to another Web page. The hypertext links are indicated by a hot spot in the PDF file where the cursor changes to a hand with a pointing finger. Use the Back button to return to previous pages in the Web browser or to return from the PDF viewer to the HTML viewer.
