how to define properties of table border with css?

I defined table.propertiesfortables {color:green; background-color:#FFFF00;
border="5" solid blue} as CSS.
I start my table with the tag: <table class=propertiesfortables>

Font is green and background yellow but I didn't get border lines.
But if I use table.propertiesfortables {color:green;
background-color:#FFFF00}
as CSS and then begin table tag with <table class=propertiesfortables
border="5" solid blue>
I get blue border line.

Why don't I get blue border lines for my table with first example with CSS
and what have
I to change to get them with CSS?

for one thing that isn't correct CSS.

try: border: solid blue 5px

for another, do you want a border around the table or the cells?:

table.propertiesfortables td{border: solid blue 5px;}

Also look up border-collapse: collapse

Styling tables with CSS is a different animal than you think.

I'm sure there must be a tutorial around somewhere on this.

Good html procedure is to use quotes
<table class="propertiesfortables"
