Q: Using exceptions for some objects in CSS I have this CSS code for my tables:
.table-hover>tbody>tr:hover {
    background-color: #f36f25;
    color:#FFFFFF;
}

i want to be able to make some rows not use this code on hover.
How can i make an exception for certain rows in my tables?

A: Give them something to identify them with (e.g. a class attribute), then use the negation pseudo-class selector (:not()) to filter them out:
<tr></tr>
<tr class="notThisOne"></tr>
<tr></tr>

.table-hover>tbody>tr:not(.notThisOne):hover {
    ...
}


A: That is possible using the :not() selector:

You can for example assign class noHover to the elements you want to skip and exclude the class from your css:
.table-hover>tbody>tr:hover:not(.noHover) {
    background-color: #f36f25;
    color:#FFFFFF;
}


A: you can create a css for the row you don't want to affect
like
<table>
<tr><td class="test">1</td><td>a</td><tr>
<tr><td>2</td><td>b</td><tr>
<tr><td class="test">3</td><td>c</td><tr>
</table>

and add your css
.test{
background: blue;
}

This is basic but you can then make your own test
