Subject: chore: update sidebar and widgets styles

I'm now using a widget that can be expanded/collapsed. It also allows
me to handle more effectively widgets overflow and to avoid styles
repetitions.
However, with stylelint rule "no-descending-specificity", I'm not sure
if the stylesheets are really logical... Maybe I should deactivate this
rule.
