1. The first step is to download both Twitter Bootstrap and jQuery. I installed versions 3.1.1 and 1.11.0 respectively. The download links are:
- Bootstrap: http://getbootstrap.com/getting-started/#download
- jQuery: http://jquery.com/download/
2. Extract the artifacts from the zip files and copy them to the "resources" directory under "webapp". Also, delete the old css file, style.css. Your directory structure should look like the image below, with the directories "css", "fonts", and "js" populated.
4. The reworked home.html page is show below.

In this page, we included the Bootstrap Template components, as we will on the other three html pages. The head section of the page is entirely the Bootstrap Template, other than the title and Thymeleaf references. Just before the body tag is closed, the two Bootstrap required js references are included, as suggested in teh Bootstrap Template.5. The reworked strategy-list.html page is show below.

A lot of changes were made to this page, with many of the changes a result of trial-and-error. At the top, you will notice a custom css style. This was added to modify the appearance of the table responsible for adding a strategy.In the tables you will notice the addition of glyphicons, to make button functionality more clear. You will also see the inclusion of div tags and liberal references to class attributes on many of the tags. These two items are responsible for the sizing and appearance of the page. In order to better understand how much space a given div occupied, I would add the following attribute inside the div tag in question: style="background:#888888;"

As with the list page, the edit page makes heavy use of div tags and the class attribute. Many of the class attributes are used for sizing, with the sizing values looking like "col-sm-#". With nearly all Bootstrap pages you will notice a common page structure inside the html body tag:div class = container
div class = row
div class = main
... content here
div
div
div
The page above is no exception. Also notice the button class attribute values and the class attribute value of "form-group" in the page. The latter does exactly what it sounds like, grouping functionality within a form.
7. The reworked strategy-delete.html page is show below.
<!DOCTYPE html>

There are two key items to note on this page. We used an input field for a consistent look-and-feel even though we do not allow input on this page. In order to make the fields read-only, we used the Bootstrap input tag attribute of disabled="disabled". The other item to note is how a button was used with the "a href=..." tag/attribute. In order to maintain a consistent look-and-feel, the following button class attributes were used:
- class="btn btn-primary"
- class="btn btn-default active"
8. Now, let's take a look at our new pages, starting with the new home.html page.
9. Here is our new strategy-list.html page.
10. And our strategy-edit.html page.
11. And finally our strategy-delete.html page.
In future posts we will look at input validation, modal dialogues, navigation/themes/Thymeleaf templates, integrating Spring Security, JPA/connection pooling, and unit testing. I changed this list slightly after working on this exercise. After these steps are complete, we should be ready to start building out the trading system core.
