Ok, this could look as a very simple question, for the people who know the answer 
Let say my component name is ‘note’ so the sccs is
note {
}
I want the buttons to be styled specially for this component so I add this into the note code
note {
button {
display: inline-block!important;
float:none!important;
margin-top:5px!important;
}
}
I added !important because if this style in out of the note code, it is required to overwrite the css priorities .
So, question, how I explain that this is the style I want for my buttons in the note.html file (if there is a question, it is because just like that it is not working so guess there is a css special spell that I didn’t know and didn’t found to be said) ?
Thanks in advance as I am feeling that this is the dumbest question in this forum, sorry about that.
