Please capitalize the first letter of the first word of a complete sentence following a colon.
Capitalization of Titles and Headings
The general rule is to capitalize the first letter of the first word in a title or heading, the first letter of all other words in a title or heading except conjunctions, articles, prepositions of fewer than four letters, and the “to” in infinitives. Here is a more detailed explanation of this rule.
Capitalize all nouns, verbs (including is and other forms of be), adverbs (including “than” and “when”), adjectives (including “this” and “that”), and pronouns (including “its”).
Hyphenated Compounds in Titles
“Hands-on Applications” or “Hands-On Applications”?
Applying this rule to the example you give yields “Hands-on Applications.“
This is because on is neither a noun nor a proper adjective; it is a preposition — or, more properly, a particle. In addition, “hands-on” constitutes a single word.
Do Not Capitalize in Titles
Capitalization in Tables
If the table is titled, use title caps for the title. That is, do not capitalize articles (a, an, the), prepositions of four or fewer letters, or coordinate conjunctions.
Capitalize only the first word of each column heading, the first word of each column entry, and proper nouns.
