5
|
* Implimentation of an Adaptivetheme Panels Layout Plugin
|
|
6
|
* A panels layout plugin on steroids and an implementation of
|
|
7
|
* hook_panels_layouts().
|
|
8
|
*
|
|
9
|
* These plugins must use the function method - Panels can support two
|
|
10
|
* methods, one that uses a function name and one that simply defines
|
|
11
|
* a $plugins array. You MUST use the function method, which requires
|
|
12
|
* correct naming of the function:
|
|
13
|
* function [theme name]_[plugin name]_panels_layouts()
|
|
14
|
*
|
|
15
|
* Adaptivetheme needs more data to build the actual CSS since it does not use
|
|
16
|
* Panels normal method of defining a static CSS file. In AT the CSS is built
|
|
17
|
* programmatically for each selected option when the user saves the theme
|
|
18
|
* settings. This is for two main reasons - first so we are optimizing the
|
|
19
|
* CSS and not adding any duplicate CSS declarations, and secondly so we can
|
|
20
|
* easily insert the CSS into the right media query in the generated stylsheet.
|
|
21
|
*
|
|
22
|
* Adding Selectors and CSS Declarations:
|
|
23
|
* Each CSS declaration is an array, keyed by an "identifier". The array items
|
|
24
|
* are selector/css pairs. For example:
|
|
25
|
* '40' => array('.five-5x20 .row-1' => 'width:40%'),
|
|
26
|
* Here '40' is the identifier, '.five-5x20 .row-1' is the selector and 'width:40%'
|
|
27
|
* is the actual CSS style.
|
|
28
|
*
|
|
29
|
* Identifiers:
|
|
30
|
* Each identifier represents a CSS style. It's basically shorthand notation for the
|
|
31
|
* actual CSS. To ensure the CSS is optimized as much as possible you should use an
|
|
32
|
* existing identifier if it exists, although you can use your own, just make sure
|
|
33
|
* to re-use them as much as possible in order to get the smallest CSS files -
|
|
34
|
* here is a full list of the existing identifiers used by AT Core Panels plugins:
|
|
35
|
|
|
36
|
Basic Widths (all must be in percentages):
|
|
37
|
|
|
38
|
ID CSS
|
|
39
|
|
|
40
|
'25' 'width:25%'
|
|
41
|
'33' 'width:33.333333%'
|
|
42
|
'40' 'width:40%'
|
|
43
|
'50' 'width:50%'
|
|
44
|
'60' 'width:60%'
|
|
45
|
'66' 'width:66.666666%'
|
|
46
|
'75' 'width:75%'
|
|
47
|
'100' 'width:100%'
|
|
48
|
|
|
49
|
Floats with widths:
|
|
50
|
|
|
51
|
'25fl' 'width:25%;float:left'
|
|
52
|
'25fr' 'width:25%;float:right'
|
|
53
|
'33fl' 'width:33.333333%;float:left'
|
|
54
|
'50fl' 'width:50%;float:left'
|
|
55
|
'75fl' 'width:75%;float:left'
|
|
56
|
'75fr' 'width:75%;float:right'
|
|
57
|
|
|
58
|
Floats:
|
|
59
|
|
|
60
|
'fl' 'float:left'
|
|
61
|
'fr' 'float:right'
|
|
62
|
'fn' 'float:none'
|
|
63
|
|
|
64
|
Stacked Regions get a specail cased identifier:
|
|
65
|
|
|
66
|
'fdw' 'float:none;display:block;width:100%;clear:both'
|
