What does +div and + div mean?

[johnsmith153]

I think this is targetting an old version of IE:

+div {
}

..but what is this:

.class1 + div, .class2 + div {
}

Thanks for any help. I'm sure this is simple.

E + F Matches any F element immediately preceded by a sibling element E.

So the CSS you are asking about is targetting the div immediately following the end of an element that has class="class1" or class="class2"

for example the div in the following code:

<p class="class1">text</p><div>something</div>
