Solution:
Look at the websites html code. Near the bottem there’s <!-- I learned HTML! Here's part 1/3 of the flag: picoCTF{ur_4_real_1nspe -->
Next look at the css and js files.
CSS file:
/* I learned CSS! Here's part 2/3 of the flag: ct0r_g4dget_402b0bd3} */
JS file:
/* I learned JavaScript! Here's part 3/3 of the flag: */
And put all the parts together for the flag.
Flag: picoCTF{ur_4_real_1nspect0r_g4dget_402b0bd3}
