As a general rule, prepositions, conjunctions and articles are not capitalized in titles.
These words are:
“a”,
“an”,
“the”,
“and”,
“buy”,
“for”,
“nor”,
“or”,
“so”,
“yet”,
“after”,
“along”,
“around”,
“at”,
“by”,
“for”,
“from”,
“of”,
“on”,
“to”,
“with”, and
“without”.
Capitalize them if they are at the beginning of a title.
