Hi all.
I use Unit test. This test add many posts.
When i validate site i have error in post – Post Format Test: Gallery. And this error in the structure of the this test.

Validation Output: 1 Error
Line 207, Column 25: Element style is missing required attribute scoped.
<style type='text/css'>
Attributes for element style:
Global attributes
media
type
scoped
Also, the title attribute has special semantics on this element.

And here this line

<style type='text/css'>
#gallery-1 {
margin: auto;
}
#gallery-1 .gallery-item {
float: left;
margin-top: 10px;
text-align: center;
width: 33%;
}
#gallery-1 img {
border: 2px solid #cfcfcf;
}
#gallery-1 .gallery-caption {
margin-left: 0;
}
</style>
