# Element Content
Hypertext literal provides interpolation via `$`. Within element
content, the ampersand (`&`), less-than (`<`), single-quote (`'`) and
double-quote (`"`) are escaped.

book = "Strunk & White"
@htl "Today's Reading: $book"
#-> Today's Reading: Strunk & White
Julia expressions can be interpolated using the `$(expr)` notation.
@htl "2+2 = $(2+2)"
#-> 2+2 = 4
To include `$` in the output, use `\$`. Other escape sequences, such as
`\"` also work.
@htl "They said, \"your total is \$42.50\"."
#-> They said, "your total is $42.50".
Within tripled double-quotes, single double-quoted strings can go
unescaped, however, we still need to escape the dollar sign (`$`).
@htl """They said, "your total is \$42.50"."""
#-> They said, "your total is $42.50".
In this document, we discuss interpolation within regular tagged
content. Interpolation within attribute values and within `")"
