Thanks for the hint, Brian Smith.

Counting each character identified as the space character, with a "new" count after each newline character between the question "What is the solution?" and the "See The Solution" link, we get the following counts:

25 15 21 | 6 15 21 14 4 | 9 20

The vertical bar above is where an additional newline character appears between the strings of spaces.

Substituting the letter corresponding to the number of its position in the Modern English alphabet spells the words --

Y O U | F O U N D | I T          *(treat the vertical bars as spaces)
