Template:Deprecated template Script error: No such module "Message box". Script error: No such module "Message box". HtmlBuilder provides a way to construct complex HTML and CSS markup by creating a tree of nodes, similar to the Document Object Model. The result is a list of codes that are more comprehensible and maintainable than if you simply concatenated strings together. It offers a fluent interface that should look familiar to any user of jQuery.

Note: This module is deprecated in favour of mw.html.


First, you need to load the module:

local HtmlBuilder = require('Module:HtmlBuilder')

Next, create the root HtmlBuilder instance:

local builder = HtmlBuilder.create()

Then, you can build HTML using the methods of the HtmlBuilder instance, listed below.

Finally, get the resulting HTML markup as a string:

local s = tostring(builder)


To allow chaining, all methods return a reference to the builder, unless otherwise stated.


local div = builder.tag('div') Appends a new child node to the builder, and returns an HtmlBuilder instance representing that new node.


builder = div.done() Returns the parent node under which the current node was created. Like jQuery.end, this is a convenience function to allow the construction of several child nodes to be chained together into a single statement.


builder = div.allDone() Like .done(), but traverses all the way to the root node of the tree and returns it.


div.wikitext('This is some [[example]] text.') Appends some markup to the node. It may include plain text, wiki markup, and even HTML markup.


div.newline() Appends a newline character to the node. Equivalent to .wikitext('\n').


div.attr('title', 'Attr value') Set an HTML attribute on the node.


div.css('color', '#f00') Set a CSS property to be added to the node's style attribute.


div.cssText('color:#f00; font-size:1.5em') Add some raw CSS to the node's style attribute. This is typically used when a template allows some CSS to be passed in as a parameter, such as the liststyle parameter of {{Navbox}}.


div.addClass('even') Adds a class name to the node's class attribute. Spaces will be automatically added to delimit each added class name.


<syntaxhighlight lang="lua"> local HtmlBuilder = require('Module:HtmlBuilder')

local root = HtmlBuilder.create()


   .wikitext('Lorem ')
       .css('color', 'red')
       .attr('title', 'ipsum dolor')
       .wikitext('sit amet')
       .wikitext('consectetur adipisicing')

local s = tostring(root)

-- s = 'Lorem sit amet

consectetur adipisicing
