The new 4J web site is designed to let authors focus on the meaning of their information and on making fast, easy changes to content.
The overall presentation of that information is handled outside of the body window by something called Cascading Style Sheets. It give the site's visitors consistency to help them find the information they're looking for.
If you're writing pages and want something to look different at the presentation layer, that is, to have a different font, color, etc. you'll need to meet with the site editor. If there's a compelling services to the site's users, the presentation can be altered and changed, but it is not a process to undertake lightly.
HTML is designed so that tags such as <h1>, <h2>, and <p> describe a page's hierarchical organization - it's logical structure. A heading <h1> tag is not meant to make your text large and bold... it's meant to introduce and describe the paragraph(s) that comes below it. A <blockquote> describes a quotation - although lots of folks use this tag as an easy way to indent any text. These tags are part of a group of tags that comprise the structural markup of a document. Using structural markup correctly allows visitors to view information using any manner of device (as described above). We use structural markup to organize our words... not to style them. We use CSS to give our words style, pizzazz, panache, and more... while preserving the underlying logical structure.
