Static, HTML files as posts
It's been around for a while, but the concept of stylised blog posts - where each post is uniquely laid out - is increasingly popular, and attractive. I'm implementing a little of that over on the Nymblog (the blog for my mobile CMS), but I've now just made the process of building and uploading stylised blog posts much easier. It's only in Django at the moment, but I'd like to port this over to WordPress. Here's how it works.
Every site is different
You download a boilerplate HTML file from the Django admin. This is generated from a template. In Django - a little like in WordPress - you can override templates, so the boilerplate file can come from my generic blog app (an app in Django is like a plugin in WordPress) or from the actual site itself. So I've created a boilerplate file specifically for the Nymbol blog.
So what's cool is that you're getting a boilerplate file tailored to that specific site. The same principle would work with a WordPress blog. WordPress would generate a fake blog post then export the HTML for the author to download.
Writing the post
There are a few HTML elements with special attributes, which the system uses to read your blog post. Here's a snippet:
<h1> <a href="#" data-bpfield="title">This is my post</a> <small>Posted <span data-bpfield="date">March 8, 2013</span> by mark</small> </h1>
data-bgfield attributes map to the title and date of the post. I can use lots of different date formats, and my app will convert that into a date that can be stored in the database. Then I look for a snippet like this:
I put the HTML of my blog post where the ellipses go.
Styling it up and adding some spice
Of course the whole point of this exercise is to allow custom styling, so to do that I look for an HTML element like this:
I put the CSS for my blog post in here, which is stored in the database in a separate field, not embedded in the HTML. Usually all the CSS rules would have to be prefixed with a class that is only applied to single blog posts.
Now here's where it gets cool. I can add images and other files to my blog post. I start by putting them in the same directory as my HTML file, then just reference them using a relative URL, like this:
<img src="kitten.jpg" />
Zip it and upload!
Once I'm happy that my blog post looks great in the browser, I zip up the files I've created and upload them via the admin area. The blog app then unpacks the Zip file, extracts the HTML and looks for any files referenced (basically anything with an
srcattribute). If it finds a file with that name inside the zip, it extracts it, adds it as an attachment to the blog post (which naturally changes its URL), then replaces that URL within the HTML and CSS.
I've added an option in my app which allows me to convert the HTML of the post body to Markdown (the syntax used by default within my blog app). The nice thing about Markdown is that it does allow HTML to be added to it, so if I untick that option, rather than converting the HTML to Markdown, it leaves it as it is. The first option is useful if you want to edit the post later on; the second is useful if it's very stylised, with lots of classes and other attributes which don't have a place within the Markdown syntax.
Probably the biggest limitation so far is that, if you reference an image within your CSS but don't include it in your HTML, the find-and-replace thing won't work. That's an easy problem to fix; I just haven't yet.
You can't provide styling for a blog post within a list, only for the single post page. This is because you don't know the ID of the blog post you're targeting when you write the HTML locally, so you can't target that specific element within a list. The way to get over this is to set an ID in the boilerplate HTML which you can use in your CSS, then replace that ID with the correct ID of the blog post when published.
There are probably other limitations, but they don't spring to mind just yet.
If this doesn't exist already, I think it'd make a really nice WordPress plugin. Sometimes it's useful to have the designed approach alongside the might of the WordPress engine, to handle comments, trackbacks, RSS, that sort of thing. Adding custom CSS for each blog post is as simple as creating a hidden custom field, and using a plugin to spit out the CSS when needed.
If it does already exist for WordPress, even better 'cos that means I don't have to write it! But I wanted it for my Django toolset, so now I have it.
