Get Really Good at Git
Say you want to fetch the value of a CSS property in a web page, one that is set using a stylesheet. How can you do so?
Say you want to fetch the value of a CSS property in a web page, one that is set using a stylesheet.
The style
property of an element does not return it, because it only lists CSS properties defined in inline styles, or dynamically.
Not the properties defined in an external stylesheet.
So, how do you do it? Use getComputedStyle()
, a global function:
const element = document.querySelector('.my-element')
const style = getComputedStyle(element)
style.backgroundColor //the RGB value
Are you intimidated by Git? Can’t figure out merge vs
rebase? Are you afraid of screwing up something any time
you have to do something in Git? Do you rely on ChatGPT
or random people’s answer on StackOverflow to fix your
problems? Your coworkers are tired of explaining Git to
you all the time? Git is something we all need to use,
but few of us really master it. I created this course to
improve your Git (and GitHub) knowledge at a radical
level. A course that helps you feel less frustrated with
Git. Launching Summer 2024. Join the waiting list!
