bitweaver Theming Tutorial

Created by: spiderr, Last modification: 26 Jun 2005 (09:29 UTC) by spiderr
This page is supposed to provide some information on how to create a theme for bitweaver.

there are some detailed informations on how the CssSchema is set up and how to use it without getting frustrated, cos "so many things change every time i change only one class".

tips, hints and tricks

browser

personally i use opera as the browser of choice due to it's state-of-the-art css and XHTML compliancy and the possibility to customise everything yourself. if you want to use opera, please visit Literary Moose's Opera Pages for information on how to turn your opera into an incredible designers tool.

for beginners, however, i recommend firefox and the webdeveloper extension. both of these browsers are cross plattform.

pick an appropriate starting theme

if you want to customise a theme according to your needs, you should pick a theme that more or less has a layout you wish to use. if you are a complete beginner, it might be useful to start with a theme that uses a table based layout as these are much more forgiving and much easier to set up. such themes include: basic, bitweaver, july4.

most other themes use a div based layout system, which is more sophisticated to set up. if your changes, however, are minor, such as modifying the colours or the font-size, you should be able to pick one of these themes as well.

source code

we use the smarty templating engine and we apply the {strip} tag to most templates to remove any excess whitespace characters. this reduces the download size of the html pages but also results in an html code that is very difficult to read. to make the source code readable, i recommend you change the following in your bitweaver install:

/util/smarty/libs/Smarty_Compiler.class.php line 337
from
{code()}
$strip_tags_modified = preg_replace('~\r\n+~m', '', $strip_tags_modified);
{code}
to
{code()}
$strip_tags_modified = preg_replace('~\r\n+~m', "\n", $strip_tags_modified);
{code}

the beginning

getting started

all themes that are available on your site are located in /themes/styles/
here you will find one theme called blank. this is a theme which contains all the most important classes and ids listed without any definitions.


to create a new theme follow these steps

copy the theme 'blank' (or whichever theme you would like to modify) and rename the folder to your new themename.
within <themename> rename the original css file to <themename>.css
hence we go from
/themes/styles/blank/blank.css
to
/themes/styles/<themename>/<themename>.css

i will assume that you have copied /blank/ as a starting point
(if not, please copy all the contents of /blank/ (appart from blank.css and blank_commented.css) to your new theme folder to take full advantage of this tutorial

taken from /themes/styles/blank/readme.css

if you wish to create a theme from scratch here is a list of all css files present in /blank/ to aid you:
  • blank.css
    • main css file with all globally used classes and more
  • customisation.css
    • contains a list of classes that can be utilised to further customise the site
  • debugwithoutline.css
    • contains a set of classes and definitions that allow you to visualise all structures used on your site
  • showdiv.css
    • if included will visualise all divs used on the site including their classes and ids
    • (works well with debugwithoutline.css)
  • showstructure.css
    • like showdiv.css but it will show you all classes and structures appart from divs
    • (works well with showdiv.css and/or debugwithoutline.css
  • showsitelayout.css
    • visualises the layout of the main tiki ids used by surrounding them with coloured lines
  • showpagelayout.css
    • draws coloured borders on one side of certain elements
    • to allow you to view the classes used without messing with your layout

including css files in your main css file

to include one of these files in your theme for debugging purposes, you can insert a line at the top of your css file
@import url("include.css");

do this for as many css files as you wish but note:
  • @import only works when it's before any definitions
  • showstructure.css | showdiv.css don't work with MSIE
    • use opera or mozilla to utilise these files
    • debugwithoutline.css only works with opera

i have tested the above with the following browsers:
  • MSIE 6.02 (nothing works regarding structures)
  • Mozilla Firefox 0.8 (everything works appart from debugwithoutline.css)
  • Opera 7.5 (everything works)

now we are ready to start with the css files.


the css

introduction

if you are coming from TikiWiki, you will notice that the css is much smaller compared to that of TikiWiki and there are very much fewer classes used.

This, however has absolutely nothing to do with the flexibility and power of the css file over the design of bitweaver. in fact, it's much easier and quicker to create a site that has an overall feel throughout. moreover, it's easy to customise particular sections exactly the way you need them if you so desire.

a certain level of css knowlegde however is required to do this.

if you feel that you 'know' css you can use the 'blank' theme as a starting point for your new theme. please consult the readme in the 'blank' folder for further information.

please note:
there is a file called base.css which is called by most themes using @import at the top of the css file. this css contains some definitions which make theming easier due to it's generic settings that set a base for difficult settings such as the css dropdown menus.


however, if you believe that there is something to be learnt from this brief tutorial, carry on reading... first of all it's important that you have a look at CssSchema, which has a basic layout of the site in terms of classes used on all output pages.

a simple example

1.
text

2.
text

3.
text


if you define the following:
{code()}
.box { font-weight: bold; }
{code}

it will result in the following:
1. text
2. text
3. text

the text in all three cases will be bold, however, if you define it like this:
{code()}
.box { font-weight: bold; }
.module { color: red; }
.admin { color: blue; }
{code}

it will result in the following:
1. text
2. text
3. text

this allows you to create a general style, look, feel using very few classes such as .box above (all the above are bold) but then go on and customise and finetune particular sections or groups of items simply.

slightly more interesting

furthermore, it's easy to modify classes that are defined within other classes using the correct selectors.

consider the following 2 pages:



{code()}

pile of foo


this is more foo


{code}



{code()}

pile of foo


this is more foo


{code}



the above only differ in the first line - either wiki or articles. as above it's easy to aply general definitions to title, and content. however it's also possible to influence, say, the content section of articles without changing settings in the wiki by defining the following:

{code()}
.articles .content { background: silver; }
{code}

the nitty gritty

consider the following page



{code()}
zero plus two equals one



i can sing

some chickens have lips


{code}



if you wish to apply a definition to all boxes you use
{code()}
.box { text-decoration: underline; }
{code}

zero plus two equals one
i can sing
some chickens have lips


if you wish to apply settings only to the boxes within the foo section
{code()}
.box { text-decoration: underline; }
.foo .box { font-weight: bold; }
{code}

zero plus two equals one
i can sing
some chickens have lips


if you wish to apply settings only to the box that has foo associated with it
{code()}
.box { text-decoration: underline; }
.foo .box { font-weight: bold; }
.foo.box { color: red; }
{code}

the result of all three definitions would be
zero plus two equals one
i can sing
some chickens have lips


please note the lack of a space in the third case as compared to the second case.
'.foo .box' vs '.foo.box'


note for MSIE: MSIE only renders .foo.box {...} if this is the actual order in which they are mentioned. i.e. .foo.box {...}
only renders if the class is called:
class="foo box"
and not:
class="box foo"


obviously you can apply a setting to only the top box by setting definitions something like this
{code()}
.box { color: blue; }
.foo .box { color: black }
{code}

zero plus two equals one
i can sing
some chickens have lips

as you can see, you have an immense amount of power if you wish to use these features.


building the theme

Well the first thing you'll probably want to start with is font style and background.
{code()}
  • {
color: blue;
font-family: sans-serif;
font-size: normal;
font-style: normal;
font-weight: normal;
text-decoration: none;
}
body {
background-color: gray;
background-image: url("images/background.jpg");
}
{code}

Take a look at CssSchema and see how you want to layout your site. Lets say you wanted #tikitop to always be 120px high with a silver background, you'd set accordingly.
{code()}
  1. tikitop {
background-color: silver;
height: 120px;
}
{code}

Next, you'd like to set a border around #tikimain.
{code()}
  1. tikimain {
border: thin solid black;
}
{code}

slideshows

slideshows are a feature of the wiki and allow you to display the wiki page in a particular way without any excess information such as columns or banner.

the slideshow pages are set up in a similar way as the wiki page and use the same classes. you can pick a theme that will be used when displaying wiki pages as a slideshow.

if you would like to use your own theme as the style for slideshows but would like something like 'larger text', you can create slideshow.css in your theme directory and add all your definitions in there. this file will be loaded in addition to your regular css and you can thus override any settings made above.

also, there is a folder called slideshows. this contains some sample slideshow.css files, which you can copy (and rename) to your theme dir, saving you some time.

so, the easiest method to enlarge your slideshow text, is to create a file called 'slideshow.css' in your theme directory and then copy and paste the content of 'slideshows/enlargetext.css' to that file and save - voila!

just to illustrate, here is the content of enlargetext.css:
{code()}
h1,.title {
font-size: 2.4em;
line-height: 120%;
}
.content {
font-size: 1.3em;
line-height: 120%;
}
{code}


the icons

in bitweaver it is possible to use your own set of icons to give the site the ultimate in customisation and theming flexibility.

currently it is possible to associate any icon with a given theme by creating an icon in the folder
/themes/styles/<style>/icons/<package>/

the extension of the icon is irrelevant. if a file with the same name as the original icon is found in the above location, it will override the original icon. this allows you to fully customise the feel of your site, even integrating icons in the mix, wihout you ever having to touch the source code.

Note: only available from version ReleaseOne onwards.

The Templates

template files can be found in the directories <package>/templates. most of the templates have the same name as the php file, using .tpl as the extension. some specific .tpl files are only used as an inclusion and can't be used on their own. these are marked with an additional _inc at the end of the filename.

If you wish to edit any one of these templates, we recommend that you create a copy of the file in your theme folder and modify the copy there. The structure in the theme folder should be
/themes/styles/<style>/<package>/<template>.tpl
You can also simply copy the template into
/themes/styles/<style>/<template>.tpl
though there may be a risk of file name collision if two bitweaverPackages have the same name.

Use the Force

If you would like to force the use of a given template for all themes but don't want to edit the source files, you can create a directory called force. Any templates found here, will override any other templates unconditionally.
/themes/force/<template>.tpl

This is an excellent technique for creating a single top_bar for your site if you use multiple themes.

This will allow easy upgrading of your system if you should require this at some point.
