responsive FAQ accordion card

hiii there, this was quite tricky because of the svg lol, and since it´s been a lot of time since I did anything with CSS my brain was kind of burning. But then everything felt familiar again... =)

however, there is a weird glitch when opening the details tag... I wonder how I can fix it, I´ve tried but failed to do so x.x

thanks for reading!

any feedback is greatly appreciated
