CSS Pseudo element syntax -

-

this vanity question, you've been warned!

i've never been fan of partial definitions such as

.flexaround1 {     display:flex;     justify-content:space-around;     align-items:center; }   .flexaround1::before {     content:""; }  .flexaround1::after {     content:""; }

today, "but if!?!?" , tried this:

.flexaround1 {     display:flex;     justify-content:space-around;     align-items:center; } ::before {     content:""; } ::after {     content:""; }

and whaddayaknow, works. thing though, i've never seen written in of tutorials or reference sites. proper css syntax or kind of unofficial somehow supported feature?

from mdn

a css pseudo-class keyword added selectors specifies special state of element selected.

a pseudo class keyword added selectors. mdn goes on give syntax, defining as

selector:pseudo-class {   property: value; }

so appears leaving out selector isn't valid css (and kind of defeats idea of pseudo class in first place anyways). leaving out selector appears still work, however, selector defaults *, applying pseudo class elements.

in program creating in python/pygame, screen.blit not working. in other programs have made, screen.blit works. error: traceback (most recent call last): file "c:...\main.py", line 46, in <module> screen.blit(sight.image, sight.rect) attributeerror: 'int' object has no attribute 'blit' the error in question caused screen variable being allocated integer instead of pygame.surface() object.perhaps accidentally rewrote variable somewhere? from can make of doing, seems stating position of blit full rect instead of coordinate. when do: screen.blit(sight.image,sight.rect) what program seeing is: screen.blit(sight.image,(sight.rect.x,sight.rect.y,sight.rect.width,sight.rect.height)) i assuming don't intend this. remember rect object consists of position, width , height. to correct code, put (sight.rect.x,sight.rect.y) location goes instead this: screen.blit(sight.image,(sight.rect.x,sight.rect.y)) the .x , .y corres
