Hihi! I strongly don't recommend publishing a guide if you are not finished with it yet. A lot of people will downvote you simply for that exact reason. Starting off with a low score will greatly hurt your chances of reaching the top when you do have the guide completed.
The coding is nice but I recommend you also add a masteries/rune section sometime later :)

Thank you, sorry, it is not finished yet :( published for some reason, please come check it again later

I like the effort you put into the text-part of the guide. You have some nice explanations, but on the other hand, you didn't put in the items. You stated you like going boots + 3 hp pots, then Sapphire Crystal, Blasting Wand going into Rod of the Ages, or if you're playing aggresively you'll get Rabadon's Deathcap, then Rylai's Crystal Scepter for the Slow and Sustain (health) and round it up with Zhonya's.

I suggest you add the items to the build, the runes and masteries as well.
That'll make this build a lot more interesting.
To round it up, make sure to select 6 items + Boot Enhancement as your full build, and make them become the 'Core items', that way, people can see what you end up having before they even click on the link, and the bonuses that the core items give will be added to the stats, which will give us a good idea of how tanky or squishy, and how strong or how weak Ahri is at lvl 18 when following your build.

That would really improve this build.
Aside from that, I'd make the images a bit smaller than that, probably about a quarter of its size.

I hope that helps ;)
