Description:
You need to develop a universal HTML email signature that will display consistently across different email clients, such as Gmail, Outlook 2010, iOS Mail. The signature must adhere to a uniform format for font, size, and data layout. All contact information should be in text format so that it can be highlighted and copied, and the links to the website and email must function correctly.
### Requirements:
1. Compatibility: The signature must display the same in all email clients.
2. Font and style: Use a single font, size, and style to ensure the signature is unified.
3. Contact information: All contact information must be selectable and copyable as text.
4. Links: Links to the website and email must be interactive.
5. Template: A template needs to be created for future use or editing for new employees.
### Steps:
1. Develop HTML template:
- Use HTML to create the signature.
- Use inline CSS to ensure compatibility with different clients (email clients often ignore external styles).
- Ensure cross-browser and cross-platform compatibility.
2. Testing on different email clients:
- Test the signature in Gmail, Outlook 2010, iOS Mail, as well as other email clients to ensure a consistent appearance.
3. Handover of the template:
- Transfer the HTML file or usage instructions for further application or editing for new employees.
