Of Dice, Dabblet, and CSS

I discovered dabblet.com some time back and never really spent much time there. Don’t get me wrong, it made a great first impression, however I am not super-talented in the CSS department, and it seems to be a tool for those who are.

I decided to return this evening and try my hand at creating some dice with nothing but CSS. I recently became a Potentate of the Rose, so this was a relevant and timely interest. After a couple hours of distracted back-and-forth, I finally had something pretty attractive.

While I don’t consider myself much of a CSS power-house, dabblet.com made the tedious process of building these die super-fun and very palatable. If you find yourself giving dabblet a run (and I suggest you do it), be sure to thank @leaverou for all of her hard work on such an awesome tool.

The final result can be seen here, or in the framed demo below.

Quickly Adding Thumbnails to WordPress Archives

Post thumbnails make archives look much more attractive in my personal opinion, yet they are not natively displayed in the otherwise-beautiful theme shipped with the latest version of WordPress, Twenty Ten.

As is the case with most WordPress stuff, this shouldn’t stop us from adding it in ourselves – this is exactly what we’ll do. I should note that I’m a student of WordPress, and wouldn’t consider myself an expert by any measure, but I do know enough to get around and do so without making a mess (correct me if I proceed to make a mess).

Our goal today is to add a small thumbnail next to our posts on the archive pages of the Twenty Ten theme. Of course what you’ll learn here can easily be applied to most themes. We’ll be making use of primarily two functions, modifying a third, and adding a few lines of CSS to accomplish this today.

We’ll be modifying only two files today, loop.php and style.css. Within loop.php we will add the code to show the image, and within style.css we’ll add the rules to style the post and the image itself. Let’s begin!

loop.php, where the magic happens

Within loop.php we will find and abundance of if-else-statements (at times I will break this down into numerous smaller files to improve readability). Within Twenty Ten version 1.1 we will find a comment on line 122 saying “How to display all other posts.” This is where we will do our initial changes. Look at the two lines following this comment:

<?php else : ?>
<div id="post-<?php the_ID(); ?>" <?php post_class(); ?>>

First we’ll want to determine whether or not the post has a thumbnail associated with it. If there is a thumbnail, we’re going to add a class to the post div which will make some changes to the formatting to accommodate the thumbnail itself. If there is no thumbnail, we’ll leave the post div as-is.

<?php else : ?>
<?php $tnail = has_post_thumbnail() ? "hasthumb" : "nothumb" ; ?>
<div id="post-<?php the_ID(); ?>" <?php post_class($tnail); ?>>
<?php the_post_thumbnail( 'thumbnail' ); ?>

There are a couple of things going on here, so let’s break them down individually. First, we’re building a CSS classname off of the presence (or lack) of a thumbnail. For anybody who might be confused with the syntax, we’re using the ternary operator to do this:

$tnail = has_post_thumbnail() ? "hasthumb" : "nothumb" ;

has_post_thumbnail() returns either true, or false. If it’s true, the value of $tnail will be “hasthumb,” and if it’s false the value of $tnail will be “nothumb”. We then carry that value down into our call to post_class() where it will be added to the beginning of a list of many other classnames generated by WordPress for this post.

Within the div that contains the post itself, we add a call to the_post_thumbnail() function and specify that we want the thumbnail size. This function assumes you want the thumbnail size even if you leave out a value. The thumbnail size is configurable in your settings (settings > media) – for my site I’m using the default 150px by 150px. If the post has a thumbnail, the HTML to show the image will be generated and the image will be placed within the resulting HTML.

Styling the Image

Now we need to style the image. Without adding our CSS, the image will sit on top of the post, which isn’t what we want. Instead, we would like to place the image to the left of the post, with a nice gutter between image and content. For this next step, let’s open up style.css and navigate down to the bottom of the file to add the following:

/* =Post Thumbnails
-------------------------------------------------------------- */
body.home div.post.hasthumb,
body.archive div.post.hasthumb,
body.search div.post.hasthumb {
  padding-left: 170px;
  position: relative;
}
body.home div.post.hasthumb img.attachment-thumbnail,
body.archive div.post.hasthumb img.attachment-thumbnail,
body.search div.post.hasthumb img.attachment-thumbnail {
  position: absolute;
  top: 0; left: -5px;
  border: 5px solid #fefefe;
  box-shadow: 0px 1px 3px #CCC;
  -moz-box-shadow: 0px 1px 3px #CCC;
  -webkit-box-shadow: 0px 1px 3px #CCC;
}

A careful look at these rules will show that they will only apply on the home, archive and search pages. Additionally, the selectors only apply to the posts that have images representing them since they are the only entries that have the hasthumb classname.

That’s it, you should be able to save all changes and begin adding a featured image for each of your posts and find it right along side your excerpt.
