The easiest way to do that is to change the size of your image to 1038*576px, that way it fils the complete space for the featured image.
I had the same issue. So I installed the free plugin: http://wordpress.org/plugins/fourteen-extended/
It takes care of that, plus other issues with Twenty Fourteen theme.
Once you install it and enable it and so on…
Go to your admin panel (left panel):
1) Appearances
2) Customize
3) TwentyFourteen Content Options “tab”
4) Check to remove whitespace… or remove background color…
5) Repeat step 4 under the “General Options “tab”
And that should fix that.
I also opted this setting, perhaps you may like it:
Check to show full width in single post (I kind of like that feature enabled for just the posts, but not the home page.)
Hannes – We are going to be having a variety of individuals adding content of various skill levels and having them find the right size image is not going to be something they will want to do.
helpful – Thanks for the tip. I tried those settings and was unable to get it to work. Using that plugin once I made any change my ‘max_posts’ => 3, variable is no longer honored and I’m back to displaying up to 6 featured items.
Thinking it may be easier to find a different theme that will work as I would like it.
rsaeks82,
I had the same problem but after some help in the forums, the code below took care of the issue (just make sure to empty your browser cache)
.post-thumbnail {
background: transparent !important;
}
a.post-thumbnail:hover {
background-color: transparent !important;
}
.featured-content {
background-image: none !important;
}
