How do I build an HTML solution in Solidity


contract TemperatureSolution{
    uint16 input,
function convertTemp(uint16 _input) public{
    return (document.getElementById("outputCelcius").innerHTML=(valNum-32)/1.8)


For reference, the HTML that it is based upon is as follows (this works, but I intend to create it on a blockchain):

<p>Type a value in the Fahrenheit field to convert the value to Celsius:</p>
<input id=“inputFahrenheit” type=“number” placeholder=“Fahrenheit” oninput=“temperatureConverter(this.value)” onchange=“temperatureConverter(this.value)”>
<p>Celcius: <span id=“outputCelcius”></span></p>

function temperatureConverter(valNum) {

valNum = parseFloat(valNum);

Solidity runs the code on the blockchain, this code I do not think makes sense. I think what you need to do is write the logic in the smart contract and then call it from HTML interface. You need web3 to let the interface talk with the smart contract.

contract TemperatureSolution{

function convertTemp(uint16 _input) public{
    return (_input-32)/1.8);

Commonly Used HTML Tags with Examples

HTML tags are keywords used in HTML to display web-pages with certain properties. They are further used for defining HTML elements. An HTML element consists of a starting tag, some content, and an ending tag. The web browser reads the HTML document from top to bottom, left to right. Each HTML tag defines a new property that helps in rendering the website.



The ‘<>’ brackets contain an HTML tag. There are two types of HTML tags- empty tags or singleton tags and container tags. Singleton tags or empty tags do not contain any content such as an image or a paragraph and hence do not need to be closed, whereas container tags should be closed.


  1. Some Content

Examples of:

Empty tag: 


Container tags: 



  1. <!DOCTYPE>
  2. Paragraph

  3. Heading

  4. Bold
  5. Italic
  6. Underline

,<style>,<script>,<link>,<meta> and <base>. <p>Text-formatting tags:</p> <p><h>,<b>,<strong>,<small>,<pre>,<i>,<em>,<sub>,<sup>,<ins>,<dfn>,<del>,<div> and <span>.</p> <p>Link tags:</p> <p><a>, <base>.</p> <p>List tags:</p> <ul>, <ol>, <li>, <dl>, <dd> <p>Table tags:</p> <table> ,<tr> , <td>, <th>, <thead>, <tbody>, <tfoot>. <p>Form tags:</p> <form>, <input>, <select>, <option>, <button>, <label>, <fieldset>, <textarea>. <p>Scripting tags:</p> <script>, <noscript> Image and Object tags: <img>, <figure>, <figcaption>, <area>, <map>, <object>.
