Report CSS errors to the devtools, both stored and live
CSS errors are reported to the Firefox developer tools in this project.
Introduction
Servo<ref>https://en.wikipedia.org/wiki/Servo_(layout_engine)</ref> is an experimental web browser layout engine. It is developed by Mozilla and written in Rust.It provides an API for hosting the engine within other software.

Project Description<ref>https://github.com/servo/servo/wiki/CSS-parse-error-reporting</ref>
We will be adding the capability of exposing CSS errors to Servo. We will be using Firefox remote developer tools to inspect and debug the code in Servo.
Program Flow
- Ensure that Servo can compile and run the given tests.
- Choose a website that is compatible with Servo and attach the remote developer tools to it.
Initial steps:
- Build Servo
- Attach remote developer tools
- Making initial changes and build Servo
- Generate css error messages
- Process error messages and retrieve cached messages
- Integrate and build again
Subsequent steps:
- Generate messages which communicate the errors to the script thread.
- Process the messages and provide support for caching them and sending them to the devtools server if it exists.
- Provide the functionality to retrieve the cached css error messages whenever requested.
