Hi all!
I’m following the course on how to build a website and currently doing the CSS lesson on colors and have a question that’s been frustrating me in the “Paint Store” exercise:
https://www.codecademy.com/paths/learn-how-to-build-websites/tracks/intermediate-css-colors-and-typography/modules/learn-css-colors/projects/color-paint-store
In step 6, the span selectors are being chosen using the .reds .base-color selector in CSS. However, in HTML, there is no “reds” class. The same holds true for the other colors (blues and greens). In HTML, these divs have a class of class=“color reds”, but in CSS, they are simply referred to as .reds.
Why does the CSS code work, and why is it coded using a class that is not defined in HTML?
Hope you guys can help me out with this nagging doubt!
Best,

in css, to select an element we do:
div {
}
in css to select a class we do:
.className {
}
to select an id we do:
#idName {
}
by using the prefixes (. for class and # for id), css knows what the selector is for
so where in html we have a class keyword, in css this is represented with a full stop (.)
I understand that. My point was that there is no class named “reds” in HTML, although CSS refers to one.
html and css are very error resistant, if there is a class in css while not used in html, the class simply never gets applied
Their is a class of reds and it’s color reds. Whitespace in a class name gives it multiple classes.

That clears it up. Thanks!
