Is it a good idea to index datetime field in mysql?
... But if you query the data with date range, such as data range from "2017-01-01 11:20" to "2018-01-03 12:12", it doesn't make SELECT query faster even though I indexed date time column... index make query fast when I use equal operation.. Am i right?

Disable webkit's spin buttons on input type=“number”?
...roll behaviour where you can scroll up and down infinitely? I've set min=0.01 (and max to some arbitrary value) in my input element, but I'd prefer to have the scrollwheel just go up and down the page. I'm using AngularJS and I can't find anything atm.
