To add an HTML component to your course, you create both XML and HTML files.
To add an HTML component to your course, you can either in-line it in

************************
In most cases, it is easiest to create your courseware structure in a
single file, the ``course.xml file``.
Starting out, it is easiest to create your courseware structure in a
single file, the ``course.xml file``. This file may contain your
entire course, but in most cases, it is convenient to split out large
chunks of content into individual files. This is typically done either
at the level of large components, such as either problems or homework
assignments.
The ``course.xml`` file would contain the
definition of all chapters (sections), sequentials (subsections), and verticals
(units) in your courseware. The courseware structure would then refer to files
for components, which are stored in a directory for each type of XBlock.
Currently, Studio, on export, places each component in its own
file. MIT ODL and edX have scripts which rechunk the file structure in
different ways.
For example, the edX Platform contains a directory called `manual-testing-complete`_ that contains a course with all component types for testing
purposes.
Course content, other than the courseware, is stored in separate directories
and files as shown in the rest of this chapter.

edX course components may be broken out of the main course.xml file

course does not contain html files, or if they are all in-lined in
their top-level components, you do not need to create an ``html``

Courseware is the main content of your course, namely lessons and assessments.

* A subsection contains one or more units. In OLX, units are represented by
``vertical`` elements.
* Course units are lessons in a subsection that students view as single pages.
A unit contains one or more components. Course components are objects within
units that contain your actual course content. For more information, see:

Problems
#################################
Use the chapters in this section to create course problems and tools.
The format for edX problems is based on the LONCAPA XML format (https://s1.lite.msu.edu/adm/help/Authoring_XML_Intro.hlp#Authoring_XML_Intro), although the two are not quite compatible. In the edX variant, problems are composed of four types of tags:
* inputtypes are similar to XBlocks. They define ways for users to enter input into the problem.
* responsetypes are graders. They define how inputs are mapped to grades.
* hinters are used to provide feedback to problems.
* Standard HTML tags are used for formatting.
In abstract, the system is designed to allow mixing-and-matching of inputtypes, responsetypes, and hinters. For example, a numerical grader could match 7+-0.1%. It would be okay to use this with any inputtype which output a number, whether this was a text box, equation input, slider, or multiple choice question. In practice, this doesn't always work. For example, in the former case, a multiple choice question would not give an output in a format a numerical grader could handle.
In addition, in many cases, there is a 1:1 mapping between graders and inputs. For some types of inputs (especially discipline-specific specialized ones), it simply does not make sense to have more than one grader.
The most general grader is customresponse. This uses a piece of Python code to evaluate the input. By design, this ought to work with any inputtype, although there are bugs mixing this with a small number of the newer inputtypes.
Like LON-CAPA, OLX allows embedding of code to generate parameterized problems. Unlike LON-CAPA, edX supports Python (and not Perl). Otherwise, the syntax is approximately identical.
