oh, cool - leave it alone for a weekend, and it works (half

)
The font color is now, what I want it to be (though I don't know, why - I guess, some cache phenomenon).
And for the .fa (make it disappear), now I stumbled over the solution as well:
Code:
.ls-questionhelp:before {
display: none;
The only thing remaining is the margin-left before the text-info (1.2em; the 2nd part of the code should work - due to the fact, that it does in the browser console, cf picture).
Code:
.fruity .text-info {
color: #35363f;
margin-left: 0;
}
.ls-quetsionhelp {
margin-left: 0;
}
