/* Fix: This will now respect your width and margin settings */
a {
display: inline-block;
width: 150px;
margin-top: 20px;
}
3. Overusing Absolute Positioning (position: absolute)
The Mistake: Using position: absolute; to push elements around the screen until they look “perfect” on your laptop, only to find the layout completely scrambled on a mobile screen.Why it happens: Absolute positioning takes elements out of the normal document flow. It makes your website completely rigid and unresponsive.The Fix: Stop using absolute positioning for general layouts. Instead, learn and use CSS Flexbox or CSS Grid to build flexible layouts.
/* Instead of absolute position, use Flexbox to center things easily */
.container {
display: flex;
justify-content: center;
align-items: center;
}
4. Hardcoding Fixed Widths (width: 800px)
The Mistake: Setting major containers or image wrappers to a hardcoded pixel size like width: 1200px;.Why it happens: A fixed pixel width looks great on a large desktop monitor, but when viewed on a smartphone (which usually has a width under 400px), your content will get cut off.The Fix: Use relative units like percentages (%), viewport width (vw), or combine max-width with a percentage.
/* Fix: The container will shrink safely on smaller mobile screens */
.main-container {
width: 100%;
max-width: 1200px;
}
5. Using the Wrong Color and Font Units
The Mistake: Using px for text sizing everywhere, making it difficult for users with accessibility needs to scale up the text on their browsers.Why it happens: Pixels are absolute units. If a user sets their default browser font larger for better readability, your px fonts will ignore their preference.The Fix: Use rem for font sizes. 1rem is typically equal to the browser’s default font size (usually 16px).
/* Fix: Responsive typography that respects user settings /
h1 {
font-size: 2.5rem; / Equals 40px on standard settings /
}
p {
font-size: 1rem; / Equals 16px on standard settings */
}
