Sorry this is so basic, but I'm a beginner.
Matt Haughey's blog, A Whole Lotta Nothing, inserts rosettes under each post title as part of his post template.
Thanks!
You can use the ::after selector to add content after all h1 elements
CSS
h1:after {
content: url("imagesource.jpg");
display: block;
}
See this live example
However, the site in question uses it as a background image. You can find this out by using the element inspector, and looking at its attributes. See the attached screenshot
Its properties are as follows:
background: url(theme-journal_black/date-header-bg.gif) no-repeat 50% bottom;
