I updated the message to be centered and red. I agree it was not the most obvious. I also tried to use bink but it looks like it does not work :P !

I should have added - it didn't take away too much but some reference eye candy - I understood what was being described and thought it was great. Thanks again and keep up all the great work, I'm still slowly making my way through the DOOM book.

While I still remember, it'd also be great to preload images — iirc in some other of your articles there were sliders that flipped through images and it was kinda annoying to have to wait for them to load.

I considered it but in the end decided against preloading.

If users don't use the slider, they will have downloaded 3MiB of images for nothing. That is especially a problem for people on a data plan.

The ideal solution would be to implement a system that preload all images related to a slider as soon as the user touches it.

I was wondering what was being described! Clicking the lower right on iOS seems to work well enough.

Thanks for all your work on these.

Thanks - you can tap on mobile as well, but Firefox on Android requires a bit of finessing to make that work. Really added a lot to the article. Thanks for the pointer.

Crap! I need to reread the whole page now. Thanks :)
