How to Override Inline Styles in CSS: Simple Methods Explained

To override inline styles in CSS, use the !important rule in your CSS declarations or increase selector specificity. Alternatively, you can modify styles dynamically with JavaScript to change or remove inline styles.

📐

Syntax

Inline styles are styles written directly inside an HTML element using the style attribute. To override them, you can use CSS with the !important keyword or write selectors with higher specificity.

element { property: value !important; } forces the style to override inline styles.
Using more specific selectors can sometimes override inline styles if !important is not used, but this is rare and depends on the context.

css

/* CSS overriding inline style with !important */
p {
  color: blue !important;
}

💻

Example

This example shows a paragraph with an inline style setting its color to red. The CSS uses !important to override that inline style and make the text blue.

html

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Override Inline Styles Example</title>
<style>
p {
  color: blue !important;
  font-weight: bold;
}
</style>
</head>
<body>
<p style="color: red;">This text will appear blue, not red.</p>
</body>
</html>

Output

A paragraph of text colored blue and bold, despite the inline style setting red.

⚠️

Common Pitfalls

One common mistake is trying to override inline styles without !important. Inline styles have higher priority than normal CSS rules, so without !important, your CSS will be ignored.

Another pitfall is overusing !important, which can make debugging and maintenance harder.

css

/* Wrong: This will NOT override inline style */
p {
  color: green;
}

/* Correct: Using !important overrides inline style */
p {
  color: green !important;
}
