Difference between `` and text

Behavior differences

While <button> and <input> seem similar, there are crucial differences:

• <button> can encase more complex items, including images and HTML content, thanks to its ability to carry child elements.
• With respect to accessibility, <button> has an upper hand as it gives more meaningful information to assistive tech via its outward description.
• When forms are submitted, <input> sends the value attribute, while the <button> transmits inner content which can be inconsistent cross-browser. Therefore, for universal understanding, use value attribute or hidden fields with <button>.

Harmonizing cross-browser compatibility

Store these cross-browser compatibility wisdom nuggets for smooth execution:

• To drop possible confusions, specify type attribute even if <button> defaults to submit.
• If <button> contains more than simple text, it's wiser to insert a value attribute for guaranteed right data submission across browsers.
• Beware! <input type="image"> serves for server-side image maps, not as a typical submit button.

Design freedom and better CSS styling

When it comes to creative flexibility, <button> is the undisputed champion:

• <button> behaves predictably with CSS styling, making padding, borders, and background color applications seamless.
• It's a designer's playground, permitting everything from plain text buttons to intricate, icon-laden buttons with tooltips.

Prefer <button> for semantic HTML

Semantic markup matters a lot for search engine ranking and assistive technologies. <button> quite expressively signals a coming action, while <input> can be a bit vague as it denotes a wide array of input types.

Choose your tool

Opt for <input> for basic needs

• Simplicity is the key.
• Traditional, no-fuss form submission.

Use <button> for high flexibility

• Where design matters.
• Complex forms that need more interactive elements.
• If accessibility and semantics play crucial roles, like ARIA-laden apps.

One step beyond: Exotic Button Behavior

Master these special scenarios to conjure impressive web forms:

• Dynamic button labels: Bend <button> to your will. Use JavaScript to change button labels and styles based on user interactions.
• Image buttons: GUI submit button? <button> encompassing <img> gives you limitless design power.
• Preventing extra clicks: Leverage JavaScript to disable the button post the initial click to stop extra form submission.
