Style guide updates to root pages

[RLHecht]

Confirm that the copyeditor checklist is complete and "heading" work in front matter is done for root pages.

Copyeditor Checklist

[ ] Search for “Servicemember” (uppercase, 1 word) on all pages.
The correct style is: “service member”
[ ] Search for “sign on,” “log in,” “login,” “log on.”
The correct style is: “sign in,” “sign out”
[ ] Scan the page for text links
Remove all periods from textual links. (Keep track in the zenhub issue of any that look awkward
because the text is super long)
[ ] Search for (ET), (CT), (PT)
Remove the parentheses around time zone. This will mostly appear where we’ve listed phone
numbers.
[ ] Scan the page for labels to change to sentence casing
• H1 titles (the title of the page) located in the front matter of the .md file
• Display titles (what shows up in the left nav) also located in the front matter
• Subheads (H2, H3, H4, which often appear as ## or ### or ####)
• Related and major links at the bottom of pages appear sometimes in a gray box (see
screenshot on the next page for a visual)
• Right column callout headings and links (see screenshot on the last page)
[ ] Note 1: Keep the following capped: Veteran / Veterans, VA.gov, proper nouns (including official
program names like Post-911 GI Bill, as well as proper nouns like Agent Orange and Gulf War)
[ ] Note 2: Keep a running list of terms here in this issue (start a new comment box below) that you're
not sure about--does VA consider them proper nouns?: "caregiver coordinator" vs "Caregiver
Coordinator"
[ ] Phone numbers
Remove the 1- before area codes, unless the information is addressed specifically to audience outside U.S. (in which case, use the +1-).
[ ] Fix hierarchy of subheads: H2-H3-H4
[ ] Add (PDF) to ends of links that link to a PDF

Add "heading" tag underneath "title" tag in front matter, copy and paste text from "title" tag and sentence case it in the "heading" tag.
