Started with css and added one mre button in html which I had forgot, the button is for adding or using DEVLENS for new folder or code base. in css I have added so many colours in start itself using variables, colours like: Kraft, mint, ink, blue, lavendar, butter, deep colours of many colours, etc. the made colour families in starting itself. so by defining and using 20 to 22 colours and 3 font families in start itself, it will be very helpful throughout the css coding.
