How to change zimbra mail login page theme

Changing the theme of the Zimbra mail login page involves modifying the CSS files that control the appearance of the login page. Here's a step-by-step guide to help you achieve this:

Prerequisites:

You have administrative access to your Zimbra server.
You have a basic understanding of CSS and HTML.

Step 1: Identify the CSS files

The Zimbra login page uses a combination of CSS files to determine its appearance. The main CSS file is zimbra.css, which is located in the /opt/zimbra/conf directory. Additionally, there are other CSS files that are used for specific components, such as login.css and header.css.

Step 2: Create a custom CSS file

Create a new file in the /opt/zimbra/conf directory, for example, custom_login.css. This file will contain the custom CSS rules that will override the default styles.

Step 3: Add custom CSS rules

In the custom_login.css file, add the following code to change the theme of the login page:

/* Change the background color of the login page */
body.login {
  background-color: #f2f2f2; /* Replace with your desired color */
}

/* Change the text color of the login page */
body.login a {
  color: #00698f; /* Replace with your desired color */
}

/* Change the font family of the login page */
body.login {
  font-family: Arial, sans-serif; /* Replace with your desired font family */
}

/* Add custom styles for specific elements, such as the login form */
#loginForm {
  width: 300px; /* Replace with your desired width */
  margin: 0 auto;
  padding: 20px;
  border: 1px solid #ccc;
  border-radius: 5px;
  box-shadow: 0 0 10px rgba(0, 0, 0, 0.1);
}

#loginForm input[type="text"], #loginForm input[type="password"] {
  width: 100%;
  height: 30px;
  margin-bottom: 10px;
  padding: 10px;
  border: 1px solid #ccc;
}

#loginForm button[type="submit"] {
  width: 100%;
  height: 30px;
  margin-top: 10px;
  padding: 10px;
  border: none;
  border-radius: 5px;
  background-color: #00698f;
  color: #fff;
  cursor: pointer;
}

Replace the #f2f2f2, #00698f, and Arial values with your desired colors and font family.

Step 4: Update the Zimbra configuration

To apply the custom CSS file, you need to update the Zimbra configuration. Run the following command:

zmprov mcf zimbraMailCustomCSS /opt/zimbra/conf/custom_login.css

This command sets the custom CSS file as the default CSS file for the Zimbra mail login page.

Step 5: Restart the Zimbra services

Restart the Zimbra services to apply the changes:

zmcontrol restart

Step 6: Verify the changes

Access the Zimbra mail login page and verify that the theme has been changed as expected.

That's it! You have successfully changed the theme of the Zimbra mail login page.
