Live CSS Editor (LCE) is jquery plugin, "themeroller like" tool for customizing your web page design. Basically, you provide json with configuration and LCE shows: live preview and CSS editor with ability to edit properties you defined. So you can control which properties can be customized.

You have to include this dependencies in your page (head):
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/jquery-ui.min.js"></script>
<script type="text/javascript" src="http://netdna.bootstrapcdn.com/bootstrap/3.0.0/js/bootstrap.min.js"></script>
<script type="text/javascript" src="../dependencies/microtpl.js"></script>
<script type="text/javascript" src="../dependencies/jscolor/jscolor.js"></script>
<script type="text/javascript" src="../dependencies/chosen/chosen.jquery.min.js"></script>
<!-- Editor -->
<script src="../source/livecsseditor/livecsseditor-2.0.js"></script>
<script src="../source/livecsseditor/editors/lceColor.js"></script>
<script src="../source/livecsseditor/editors/lceFont.js"></script>
<script src="../source/livecsseditor/editors/lceBackground.js"></script> In the page's body provide div where editor will be placed - give it enough space. Note: there cannot be 2 LCEs on a single page.
<div id="livecsseditor"></div> Init LCE when document is ready, ex.
$(document).ready(function(){
$('#livecsseditor').livecsseditor({
pages: {
'targets/simple.html': {
name: 'First Page',
def: {
'h1':{
name: 'Heading',
props:['color','background-color','font-family','font-weight','text-align'],
labels: ['Color','Background color','Font','Font Weight','Align'],
description: 'Update heading here',
editorsConfig:{
"font-family": {
"names": ["Verdana","Arial", "Times New Roman"]
}
},
iconClass: "glyphicon glyphicon-star"
},
'p,span':{
name: 'Text',
props:['font-size','color'],
labels: ['Font size','Color'],
editorsConfig:{
"font-size": {
"fixedValues": ["original","10px","11px","12px"]
}
},
iconClass: "glyphicon glyphicon-font"
}
}
}
}
});
});| option | description | default | possible values |
|---|---|---|---|
| pages | JSON definition of pages, styles and properties to be customized | null | Object |
| layout_tpl | Micro template layout | default template | String |
| props_tpl | Micro template property list layout | default template | String |
| hoverColor | Background color or selected element in the live preview | #faf3ba | String |
Get customized css string for defined page pagePath or all pages
Returns: String
- pagePath, Type: String, Default: null
$('.selector').livecsseditor('getCss','page.html');</pre>Get customized JSON Object for defined page pagePath or all pages
Returns: Object
- pagePath, Type: String, Default: null
$('.selector').livecsseditor('getJson','page.html');</pre>Set JSON Object for customized prepared style
- jsonObject, Type: Object, Default: null
$('.selector').livecsseditor('setJson',{
"page.html":{
"h1": {
"background-color": "#F9FF40",
"color": "#FA2B46"
}
}
});Follow standard installation. Start livecsseditor when the document is ready.
$('#livecsseditor').livecsseditor({
pages: {
'targets/simple.html': {
name: 'First Page',
def: {
'h1':{
name: 'Heading',
props:['color','background-color','font-family','font-weight','text-align'],
labels: ['Color','Background color','Font','Font Weight','Align'],
description: 'Update heading here',
editorsConfig:{
"font-family": {
"names": ["Verdana","Arial", "Times New Roman"]
}
},
iconClass: "glyphicon glyphicon-star"
},
'p,span':{
name: 'Text',
props:['font-size','color'],
labels: ['Font size','Color'],
editorsConfig:{
"font-size": {
"fixedValues": ["original","10px","11px","12px"]
}
},
iconClass: "glyphicon glyphicon-font"
}
}
}
}
}); Options JSON has the following structure:
- pages
- page url URL to a page to be customized
- name Descriptive page name
- def
- element css selector CSS selector of a DOM element
- name Descriptive element name
- props Array of editable CSS properties
- labels Array of descriptive names of editable properties
- description Description of the current element
- iconClass Optional element's icons css class
- editorsConfig Optional properties for particular editors
- property Value for each key is configuration for particular editor
- element css selector CSS selector of a DOM element
- page url URL to a page to be customized
Livecsseditor let you manage multiple pages from the same screen.
In this example we have included custom position and size editors for in place, WYSIWYG editing. After standard installation you need to include these 2 editors:
<script src="../source/livecsseditor/editors/lceSize.js"></script>
<script src="../source/livecsseditor/editors/lcePosition.js"></script>Options JSON has to include definition for this properties on proper elements:
'div.resizable':{
name:'Resizable',
props:['width','height'],
iconClass: "glyphicon glyphicon-fullscreen"
},
'div.movable':{
name:'Movable',
props:['left','top'],
iconClass: "glyphicon glyphicon-fullscreen"
}Note that movable element needs to have absolute position in order to be draggable.
Selecting a background image for your elements is more of a backend task, thus you might want to create custom editor with integrated file manager or similar.
Still, there's a simple built-in option. Basically, it's a simple select box with predefined options provided by you.
'div.resizable':{
name:'BG Image',
props:['background-image'],
labels: ['Background Image'],
description: 'Choose BG Image',
editorsConfig:{
"background-image": {
"urls": ["images/bg1.jpg","images/bg2.jpg", "images/bg3.jpg"]
}
},
iconClass: "glyphicon glyphicon-fullscreen"
}livecsseditor has two methodsgetCss andgetJson for you to store somewhere definition of made customization. On the hand,setJson provides a way to load styles from JSON object:
Options JSON has to include definition for this properties on proper elements:
//css button
$('#cssBtn').click(function(){
alert($('#livecsseditor').livecsseditor('getCss','targets/complex.html'));
});
//json get button
$('#jsonBtn').click(function(){
console.log($('#livecsseditor').livecsseditor('getJson','targets/complex.html'));
});
//json set button
$('#jsonSetBtn').click(function(){
$('#livecsseditor').livecsseditor('setJson',{
"targets/complex.html":{
"h1": {
"background-color": "#F9FF40",
"color": "#FA2B46"
}
}
});
});Whenever you are not satisfied with built-in editor or you need some custom editing logic, you can easily plug in your custom editing function.
In this example we attached our custom color editor. Let's say we want our users to choose just red or green color, peace of cake:
$.fn.livecsseditor.setPropertyEditor(['color','background-color'],
function customColorEditor(customizer, vars, config){
var $select = $('<select class="form-control"></select>'),
html = '',
options = {
"original": "",
"#FF0000": "Red",
"#00FF00": "Green"
};
vars.container.append($select);
for(var value in options){
var selected = '';
if (vars.value == value) {
selected = ' selected="selected"';
}
html += '<option value="' + value + '"' + selected + '">' + options[value] + '</option>';
}
$select.html(html).change(function(){
vars.setValue($(this).val());
})
});We attached editor function using$.fn.livecsseditor.setPropertyEditor. Basically, we define in this call which properties we edit and callback function. During callback execution, livecsseditor provides 3 arguments:
- customizer - livecsseditor instance
- vars - running environment: value, setValue function, etc.
- config - editor local configuration
Whenever you want to limit available options to predefined set, there's no need to create custom editor, you can just define property editor configuration:
$('#livecsseditor').livecsseditor({
pages: {
'targets/complex.html': {
name: 'Complex page',
def: {
'h1':{
name: 'Heading',
props:['font-size'],
labels: ['Font size'],
editorsConfig:{
"font-size": {
"fixedValues": ["14px","15px", "16px"]
}
},
iconClass: "glyphicon glyphicon-star"
}
}
}
}
