# Cascading Style Sheets (CSS)

## 1. Introduction

ShapeChange uses CSS to define the appearance of an HTML feature catalogue.

## 2. CSS for Single Page HTML Feature Catalogue

For a plain HTML feature catalogue (target parameter outputFormat is html), CSS is embedded in the resulting HTML page.

In order to adapt this CSS, either modify the HTML page or - if you are going to create multiple single page HTML feature catalogues with modified styling - customize the html.xsl file (see feature catalogue target parameter xslhtmlFile) directly.

## 3. CSS for Frame-Based HTML Feature Catalogue

The appearance of a frame-based HTML feature catalogue is defined by CSS instructions that are contained in a separate file, called 'stylesheet.css'.

When creating a frame-based HTML feature catalouge, by default ShapeChange looks for the file called 'stylesheet.css' in the folder that contains the XSLT for the feature catalogue transformation (see feature catalogue target parameter xsltPath). This CSS file is copied to the resulting feature catalogue, more specifically into the top directory that contains the index.html file.

In order to modify the stylesheet.css that is used by the frame-based HTML feature catalouge, you can:

1. modify the stylesheet.css in the resulting feature catalogue

2. modify the stylesheet.css template that is used when a feature catalogue is created

The second option is better if you need to create many feature catalogues with modified CSS, or in case that you might need to create the same feature catalogue multiple times (e.g. during model development). You can point ShapeChange to a local directory that contains the modified stylesheet via the target parameter cssPath.

### 3.1. Banner Settings

Per default, ShapeChange adds the name of the feature catalogue (configured via target parameter name) as heading in the top section - let us call it 'banner' - of the resulting HTML frame structure. If desired, you can also add a graphical image as background of this banner. To do so, modify the following settings in the stylesheet.css:

- header: add background-image setting with the path to the image - either an absolute path to a location on the web, or a path relative to the location of the stylesheet.css in the folder of the resulting feature catalogue; example: background-image: url("./logo.png");

- div.contentDiv: set the top setting to the height of the image (e.g. top: 300px) - for small images, pick a suitable height so that the heading with the feature catalogue name is visible

- h1.banner:

  - set the height to the height of the image (e.g. height: 300px) - for small images, pick a suitable height so that the heading with the feature catalogue name is visible

  - the horizontal placement of the heading text can be adjusted via the margin-left setting; if, for example, you want the heading to appear right beside the image, set margin-left to the width of the image (e.g. margin-left: 400px;)
