This commit updates the CSS styles for better consistency and correctness. The changes involve:
1. Replacing 'z-index: -1px' with 'z-index: -1' to correct the z-index value. The value should be an integer, not a length with a unit.
2. Replacing 'font-size:bold;' with 'font-weight:bold;' to set the font weight to bold properly.
Please note that I haven't tested the changes yet, but they should have a positive impact on the overall appearance and functionality of the elements styled with these CSS rules.
This commit refactors the CSS styles by removing unnecessary closing parentheses from the box-shadow declarations and redundant empty color declarations. Additionally, it corrects the missing CSS property values in the .btn_submit and #mb_login_notmb p rules for proper styling.
The changes do not affect the visual appearance of the elements but make the CSS code cleaner and more maintainable.
In accordance with the PHP RFC deprecating the curly brace syntax for accessing array elements and string offsets, this commit replaces all instances of {} with [].
By making this change, we ensure the codebase remains compliant with the recommended syntax, enhancing code readability and maintainability. The deprecation of curly brace syntax was done to align with best practices and promote a consistent code style.
