Should I Use `!important` in CSS?

The Dangers of !important in CSS

When working with CSS, it's tempting to use the !important declaration to override other styles for specific elements or properties. While this may seem like a quick fix in certain situations, it can lead to maintenance nightmares in the long run.

In your case, you encountered an issue with element height being incorrectly displayed due to inline style attributes injected by JavaScript. By adding !important to the height property in your CSS, you essentially overrode the inline style and corrected the display issue.

However, this approach should be used with caution. !important ignores the cascading order of CSS, meaning it can easily overwrite other styles that you or other developers have intentionally set. This can lead to unintended consequences and difficulty maintaining the codebase.

A better approach would be to identify why the JavaScript is injecting inline styles that override your CSS. By adjusting the JavaScript code or modifying the specificity of your CSS rules, you can achieve the desired display without resorting to !important.

While !important can be a useful tool to address specific situations, it should be considered a last resort. Overusing it can create a tangled web of styles that are difficult to maintain and can lead to unexpected behaviors.

In general, it's better to avoid using !important and instead focus on organizing your CSS in a structured and logical manner, using appropriate selectors and specificity rules to control style inheritance and precedence.
