HOWTO: Mood icon to the left of metadata

  • Dec. 15th, 2006 at 4:04 PM
UPDATED (3/03/08): This function has been updated to add the custom friends groups to the metadata. Code is based on kunzite1's similar modifications for every other style. (Comments to this entry before the update probably won't make sense anymore.)

Since you need to override the print_metadata() function, this modification will require a custom theme layer, and therefore, a paid account.
# Change these to desired label.  Remove the colons if using images.

Set your theme layer to be the active one from the Choose Journal Style page by clicking on "Your Custom Layers" in the left sidebar, then selecting "Apply Theme" under the appropriate layer.

Add the following CSS to your layer or custom CSS box:
.lj-currents ul {margin-bottom: 0px;}
/* These two lines only necessary when using images as headers */
.asset-tags-header {padding-right: 0px; width:auto;}
.asset-tags-list {margin-left: 0px;}

Thank you so much for your help!

Ok, I've got my layer being used (yay) and it all seems to be working fine. The only problem is that I didn't actually want the mood icon to the left of the metadata. *facepalms*

I wish I could figure all this stuff out on my own, because I know that you've got better things to do. Is there something I can change in the code to put the mood icon back to the right of the metadata where it was originally, and still have the location come after mood?

Unfortunately, putting the mood icon left of the metadata is what that function does. Changing the order of the metadata is just a side benefit. =P I was actually going to adapt kunzite1's later version for Expressive within the next few days, since it's been kind of slow here. I think that new function will be a little more configurable.

BTW, is it totally weird of me that any time I first glance at your icon, I see the rainbow coming out of the guy's nose?

I know. *chuckles* I was just kind of hoping that maybe if I rearranged something maybe it would go back to the original position and I'd still be left with the loc_after_mood but this is cool like it is for now, I appreciate the help and the coding! I'll keep an eye out for the adaptation whenever you get around to it.

And OMG no it's not weird of you. At first glance I see it too, which is part of what makes me love that icon so much lol.

Let me see if I understand you here. You are planning on adapting kunzite1's code for rearranging metadata (I'm assuming that's what it does after.. staring at it for a couple of minutes XDDD) for use with Expressive? That is absolutely excellent! O_O; I welcome your plan with open arms xD;
