Changing the Logo

EmpowerID provides an overrides directory within the EmpowerID Web CDN that can be used to customize the theme of the Web site. This allows you to change the default look and feel of the site to match your corporate brand or that of a partner who uses the site. To do so, you place the appropriate CSS files, images and scripts within the specified folders of the overrides directory. EmpowerID then "picks up" your files from the overrides directory, replacing the application's default files with them. This topic demonstrates this by showing you how to change the logo that appears on each page of the Web site.

Changing the logo involves overriding the CSS class that defines the image. In EmpowerID, this class is the eid-logo class, which contains properties that define the class, such as the background and the background size. When replacing the logo, you override the properties of the class, replacing the default values with yours. For eid-logo, these properties are as follows:

  • background - Specifies the logo
  • background-size - Specifies the size of the background
  • display - Specifies the box type for the logo
  • width - Specifies the width of the logo
  • height - Specifies the height of the logo
  • text-indent - Specifies the horizontal space the first line of text should be moved from the starting edge
  • overflow - Specifies what to do when the size of the image is larger than the background
  • margin-top - Specifies the distance between the logo's top border and the logo's outer edge

To override the logo, you create an overrides.css file with a custom definition for the eid-logo class and place that file within the overrides directory mentioned above. The path to the file is critical as EmpowerID will not incorporate your changes if the path is incorrect. In a default installation of EmpowerID, the path looks as follows: 

\Program Files\TheDotNetFactory\EmpowerID\Web Sites\EmpowerID.Web.Cdn\Overrides\Themes\EmpowerID
This path should already exist; if it does not, you need to create it.

This topic demonstrates how to change the default logo of the EmpowerID Web application and is divided into the following activities:

To add the custom logo to the overrides directory

  1. From your EmpowerID server, navigate to \Program Files\TheDotNetFactory\EmpowerID\Web Sites\EmpowerID.Web.Cdn\Overrides\Themes\EmpowerID\Images. If you are missing any the folders, please create them.
  2. Place your custom logo in the Images folder, as shown by the below image. In the image, the name of the logo is ABLogo; however, the name is not important.

To override the eid-logo CSS class

  1. Using any text editor create a CSS file named overrides.css and place it in the EmpowerID folder that is located within the EmpowerID Web CDN Overrides directory. The path to the file should be "\Program Files\TheDotNetFactory\EmpowerID\Web Sites\EmpowerID.Web.Cdn\Overrides\Themes\EmpowerID\overrides.css."

  2. Add code to overrides.css to replace the default logo with your custom one. This code needs to override the properties of the eid-logo class that you want to change. In the example, we are changing the following properties:
    • background - specifying the custom logo
    • background-size- specifying the size of the background
    • width - specifying the width of the logo
    • height - specifying the height of the logo
    • margin-top - specifying the distance between the logo's top border and the logo's outer edge
    /*custom logo*/
    .eid-logo{
         background: url(images/ablogo.png) no-repeat;
         background-size: 240px 63px;
         width: 242px;
         height: 63px;
         margin-top: 5px;
     }
  3. Save your changes.

To test the CSS override

  1. Open your browser and navigate to the EmpowerID Web application in your environment.

    2. You should see that the default logo has been updated to reflect the changes you made.

    You can revert back to the original logo by removing the eid-logo class from the overrides.css file.
