Description:
In this tutorial we will create some range sliders using HTML5 CSS SASS and Javascript.
The HTML part is not log so our main focus is on the CSS/ SASS part of the project and also just a tinch of DOM manipulation using JavaScript by selecting element from the DOM with the help of queryselector and queryselectorAll in order to grab on to some ID`s from the html .
I particularly like SASS because it gives my the possibility to create partial elements which are reusable in other later projects.
