Few Examples Of How EM Works

Here are some unique and better examples of how EM works in different scenarios, including nested elements, scaling effects, and practical use cases.

Example 1: Nested Scaling Effect

When an element inherits em values, it multiplies based on its parent’s size.

HTML:

<section>
    <article>
        <p>This is an example of nested EM scaling.</p>
    </article>
</section>

CSS:

section {
    font-size: 16px; /* Base size */
}

article {
    font-size: 1.5em; /* 1.5 times the section size (16px * 1.5 = 24px) */
}

p {
    font-size: 2em; /* 2 times the article size (24px * 2 = 48px) */
}

Result:

• <section> = 16px
• <article> = 24px (16px × 1.5)
• <p> = 48px (24px × 2)

✅ EM scales dynamically based on its parent, causing exponential growth in nested elements.

Example 2: Button Scaling for Accessibility

Use em for button padding and font sizes, so it scales proportionally.

HTML:

<button class="btn">Click Me</button>

CSS:

.btn {
    font-size: 1.5em; /* 1.5 times the body font size */
    padding: 0.5em 1em; /* Dynamic spacing */
    border: none;
    background: blue;
    color: white;
    cursor: pointer;
}

Why It’s Useful?

• If the user increases the base font size, the button scales proportionally.
• More accessible for users who adjust font sizes for readability.
