10 Simple CSS Tweaks to Instantly Boost Readability and Layout

Limit Content Width

body {
  max-width: clamp(320px, 90%, 1000px);
  margin: auto;
}

Constraining the body width to a responsive range makes the page look more comfortable and centered on any screen.

Increase Text Size

body {
  font-size: 1.25rem;
}

Raising the base font size improves readability, especially on devices where the default 16 px feels small.

Increase Line Height

body {
  line-height: 1.5;
}

Adding more vertical space between lines breaks up dense text blocks and makes paragraphs easier to scan.

Limit Image Width

img {
  max-width: 100%;
}

Setting images to a maximum width of 100 % prevents horizontal scrolling and keeps visuals in line with surrounding text.

Limit Paragraph Width

p {
  max-width: 65ch;
}

Constraining paragraph width to about 65 characters reduces the “text wall” effect and improves line length for better reading flow.

Balanced Heading Wrapping

h1, h2, h3, h4, h5, h6 {
  text-wrap: balance;
}

Using text-wrap: balance distributes long headings across lines more evenly, improving visual balance.

Match Form Control Color to Site Theme

body {
  accent-color: #080; /* your preferred accent */
}

Setting accent-color lets native form controls inherit the site’s accent hue, creating a more cohesive design.

Easy‑to‑Read Zebra Table Rows

:is(tbody, table) > tr:nth-child(odd) {
  background: #0001; /* or #fff1 for dark themes */
}

Alternating row colors make tabular data easier to scan horizontally.

Add Padding to Table Cells and Headers

td, th {
  padding: 0.5em;
}

Adding padding creates visual separation between cells, improving accessibility and readability.

Reduce Motion for Accessibility

@media (prefers-reduced-motion) {
  *, *::before, *::after {
    animation-duration: 0s !important;
    transition: none !important;
    scroll-behavior: auto !important;
  }
}

Respecting the prefers-reduced-motion media query removes animations for users who prefer a static experience.
