Trying to override Table Row settings

I'm using these rules

#MyTable tr:nth-child(odd) {
}

#MyTable tr:nth-child(even) {
}

I'm trying to put a table inside on开发者_如何学运维e of the rows:

#InnerTable {
}

But it seems to be inhereting the style of MyTable. How do I override The MyTable settings for my inner table so that it has no effect on InnerTable's style?

You could rewrite your existing rules to be more specific. Using the child selector you could have:

#MyTable > tr:nth-child(odd) {}
#MyTable > tr:nth-child(event) {}

This limits the rule to tr elements which are directly contained within an element with the id #MyTable. Then you can add specific rules for your #InnerTable as well:

#InnerTable > tr:nth-child(odd) {}
#InnerTable > tr:nth-child(event) {}

The E > F selector "Matches any F element that is a child of an element E" whereas the normal E F would "Match any F element that is a descendant of an E element".

Bare in mind that if your tr are in fact contained within a tbody element as they should be to create a valid table element,

<table id="MyTable">
    <tbody>
        <tr>
            ...
        </tr>
    </tbody>
</table>

The your rules would have to reflect this:

#MyTable > tbody > tr:nth-child(odd) {}
#MyTable > tbody > tr:nth-child(event) {}

#InnerTable > tbody > tr:nth-child(odd) {}
#InnerTable > tbody > tr:nth-child(event) {}

Or you could specifically reset all options in a rule applied later on (avoid if possible, since this leads to a lot of meaningless repetition):

#MyTable #SomeOtherTable tr:nth-child(odd) {
    some-property: the-default;
}

For more ideas on how to be more specific (reducing the set of elements your rules will apply to) check out the W3C documentation regarding selectors.

I found the answer! If you just try to specify a class for the td, it only works on every other row.. to make it work everywhere, in the css file, add the keyword !important for example:

.correct {
    background-color:#C9FDC1 !important}    
.incorrect {
    background-color:#FDB5B7 !important}

Do this at the bottom of your css file, after the nth child rule. The on your table, use td class="correct" or td class="incorrect"
