HTML
<p>
There were doors all round the hall, but they were all locked; and when
Alice had been all the way down one side and up the other, trying every
door, she walked sadly down the middle, wondering how she was ever to
get out again.
Suddenly she came upon a little three-legged table, all made of solid
glass; there was nothing on it except a tiny golden key, and Alice's
first thought was that it might belong to one of the doors of the hall;
but, alas! either the locks were too large, or the key was too small,
but at any rate it would not open any of them. However, on the second
time round, she came upon a low curtain she had not noticed before, and
behind it was a little door about fifteen inches high: she tried the
little golden key in the lock, and to her great delight it fitted!
