CTR mode uses AES as a stream cipher so that the cipher text length is the same as the plain text length (plus the IV). So, that said, CBC mode xor’s each byte of plaintext with the previous block’s corresponding ciphertext before encrypting.

WebCTR is counter-mode. The gist is that: You encrypt a counter stream. A counter stream is just the stream of values you get from a counter. For example, 1, 2, 3, 4, etc.. Assuming that your encryption method was secure, then your counter stream should be pseudo-random to anyone who doesn't know how you encrypted it.
