Style Input Fields

Improve the appearance of text fields, email fields, phone numbers, and textareas with custom CSS.

.wpcf7 input,
.wpcf7 textarea,
.wpcf7 select {
    width: 100%;
    padding: 12px;
    border: 1px solid #dcdcdc;
    border-radius: 8px;
    font-size: 16px;
    box-sizing: border-box;
}

This creates cleaner and more user-friendly form fields.

Customize the Submit Button

Your submit button should stand out and encourage visitors to complete the form.

.wpcf7 input[type="submit"] {
    background: #2563eb;
    color: #ffffff;
    border: none;
    padding: 14px 28px;
    border-radius: 8px;
    cursor: pointer;
    transition: .3s ease;
}

.wpcf7 input[type="submit"]:hover {
    background: #1d4ed8;
}

Style Labels

Readable labels improve form usability.

.wpcf7 label {
    display: block;
    font-weight: 600;
    margin-bottom: 8px;
}

Customize Error Messages

Highlight validation messages so visitors know exactly what needs attention.

.wpcf7-not-valid-tip {
    color: #dc2626;
    font-size: 14px;
}

.wpcf7-response-output {
    border-radius: 6px;
    padding: 12px;
}

Add More Space Between Fields

Proper spacing makes forms easier to complete.

.wpcf7 p {
    margin-bottom: 20px;
}

Create Two-Column Layouts

For longer forms, displaying fields side by side can reduce scrolling.

.form-row {
    display: flex;
    gap: 20px;
}

.form-row > div {
    flex: 1;
}

This layout works well for fields like First Name and Last Name.

Responsive Design

Ensure your forms work well on mobile devices.

@media (max-width: 768px) {

.form-row {
    flex-direction: column;
}

}

Responsive layouts improve usability across phones, tablets, and desktops.

Style File Upload Fields

Make upload fields more visually appealing.

.wpcf7 input[type="file"] {
    padding: 10px;
}

Improve Accessibility

Good accessibility benefits all users.

  • Use sufficient color contrast.
  • Keep font sizes readable.
  • Ensure buttons are easy to click.
  • Use visible focus states.
  • Avoid relying on color alone for validation.

Common CSS Mistakes

  • Using overly specific selectors.
  • Editing plugin files directly.
  • Forgetting responsive layouts.
  • Using fixed widths.
  • Making buttons too small.
  • Ignoring accessibility.
