What is a style element that should be avoided when writing accessible and usable alert and warning messages?

When writing accessible and usable alert and warning messages, it's essential to avoid using jargon or overly technical language that may confuse users. Messages should be clear and straightforward, ensuring that all users, regardless of their background or expertise, can easily understand the information being conveyed. Additionally, avoid excessive use of color or visual elements that may not be perceivable to individuals with visual impairments, as this can hinder overall accessibility.
