NOTE: I am not currently supporting this plugin. It may not be working in with the current version of Discourse.
This plugin allows the user to add a simple responsive grid to a Discourse post.
Follow the Install a Plugin howto, using
git clone https://github.com/scossar/discourse-grid as the plugin command.
Once you've installed it, review the settings under plugins in the admin section of your forum.
This plugin whitelists the following classes for use in div and figure tags.
grid-row(the outer container for a grid)one-quarter(sets with to 1/4 of it's parent)three-quarters(sets with to 3/4 of it's parent)one-third(sets with to 1/3 of it's parent)two-thirds(sets with to 2/3 of it's parent)half(sets with to 1/2 of it's parent)full(full width - useful for maintaining the side-margins)center(add to a width class to center an element in a grid row)
To add a grid to a post, first create a div of class grid-row to contain the grid:
<div class="grid-row"></div>
The grid-row can then be divided into columns using the whitelisted size classes. For example this code will give you a post with two columns, each with a width of 50%.
<div class="grid-row">
<div class="half"><img src="/uploads/default/original/1X/0c3fe002178b74a8aa061b70d84d1438a4ce4bc5.jpg" width="690" height="426">
</div>
<div class="half">
pellentesque adipiscing. Diam libero, magna orci. Pellentesque elit.
Blandit orci. Placerat ipsum, integer praesent scelerisque, dapibus adipiscing donec.
</div>
</div>
This will give you two columns of text:
<div class="grid-row">
<div class="full">
##Two columns of text with a full width heading
</div>
<div class="half">
**Dis at congue mus sagittis** libero lectus velit condimentum consectetur vitae sem vestibulum parturient condimentum cum.
<img src="/uploads/default/original/1X/0c3fe002178b74a8aa061b70d84d1438a4ce4bc5.jpg" width="690" height="426">
ac suscipit id pretium. Ante et quam non porttitor sociis adipiscing sem orci vestibulum sit ad nisl consequat eleifend a ut.
</div>
<div class="half">
sociosqu placerat tincidunt a sem libero lectus velit condimentum consectetur vitae sem vestibulum parturient condimentum cum.
Ut a condimentum sit vivamus dis ut vulputate adipiscing a laoreet lacus egestas a ut suspendisse nibh purus mattis.
</div>
</div>
This will give you a centered image with a width of two-thirds of the post area:
<div class="grid-row">
<div class="two-thirds centered">
##Centered Two-thirds width
<img src="/uploads/default/original/1X/0c3fe002178b74a8aa061b70d84d1438a4ce4bc5.jpg" width="690" height="426">
</div>
</div>
##Markdown and linebreaks
The Discourse markdown parser, will, by default, convert line breaks in your post into <br> tags.
This can make a mess of the grid. There are a few ways around this.
The first is to write your markup without useing line breaks between tags. This works, but it is difficult to read and debug.
The second is to select the 'traditional markdown linebreaks' setting in the Discourse admin section. This setting requires two trailing spaces for a linebreak. This allows you to write readable markup that displays properly on the grid.
The third option is to select the discourse-grid plugin option 'grid remove line breaks'.
This option will search through all .grid-row divs and remove all <br> tags.
If the vertical layout of your post seems wrong, with one element pushed down compared to another, try adding or removing a line break. With a bit of practice you will see how it works.
##Responsive breakpoint
At < 600px window width, all grid elements revert to having a width of 100% of the post area.
