I agree with you, about personal tastes.

I asked him to have a start point.

I'm used to use Sigil to remove all the CSS and them get a "pure"epub to Kindle deal with the file. But....I need a little tweak on line spacing and margins.

As an example, here's part of the stylesheet I normally use. Most of the work is done in the body where I indulge my preference for left justified (ragged right) text. Change that to text-align: justified; if you prefer justified text. The p tag is the basic paragraph with subsequent paragraphs getting an indent. The dropcap code give a visibly larger bold look while not being so enthused that it dominates the page. The chapnumber is basically the chapter number. Bold, centered and not taking up half a page on my screen. There is quite a bit more but this is the basics for me.

body {
    display : block;
    font-size : 1em;
    line-height : 1.2;
    margin : 0 0 0 0;
    padding : 0 0 0 0;
    text-align : left;
    widows : 1;
    orphans : 1;
}
p  {
    padding : 0 0 0.2em 0;
    text-indent : 0;
}
.subsq {
    text-indent : 4%;
}
.chapnumber {
    font-size : 1.5em;
    margin-top : 2em;
    margin-bottom : 1.5em;
    page-break-after : avoid;
    text-align : center;
    font-weight : bold;
}
.dropcap {
    font-size : 1.5em;
    margin-top : -0.09em;
    font-weight : bold;
}
