Adding Disqus to a Ghost Blog running a Casper-based theme without editing any files
I noticed that there weren't any writeups for using code injection to add Disqus comments to a ghost blog. Everything assumes you're comfortable with editing your theme (and thus being responsible for maintaining a fork, urk).
So, I used the steps below to add to Disqus comments to my blog running a [Casper fork]( If your theme varies wildly from Casper, you'll be able to get by just by updating the css selectors in the javascript. If all that is a bit much for you, leave a comment and a link to your site and I'll give you what your versino of the code would be.
## Code Injection to the rescue
So! Here's the scoop
1. **Set up your disqus**. You're a grownup, you'll figure it out.
2. Go to your blog admin's **`Code Injection`** section (
3. Add this code to the **`Blog Header`** section to style up your disqus.
Don't want it getting too wide now, do we?
#disqus_thread {
width: 80%;
max-width: 710px;
margin: 3rem auto 0;
4. Add this code to the **`Blog Footer`** section.
Make sure to replace the disqusSite value with whatever your disqus subdomain is (for example, mine's `` so I put `'novaugust'` in there).
<!-- disqus -->
// Only inject comments if you're on a post page.
var article = $('.post-template main article');
var disqusSite = 'YOUR-DISQUS-SUBDOMAIN-HERE'; // Yo! You gotta customize this bit to you!
if (article.length) {
article.after('<div id="disqus_thread"></div>');
// this is the code you get from disqus
(function() {
var d = document, s = d.createElement('script');
s.src = '//' + disqusSite + '';
s.setAttribute('data-timestamp', +new Date());
(d.head || d.body).appendChild(s);
## Caveat
This won't provide the unique-ifying `` to disqus. If that's a concern for you, you'll just have to update your theme.
