Besides countless built-in calculators, you can also do math on your desktop using HTML code to build yourself. To create a computer from HTML, you need to learn some basic knowledge of this programming language and then copy the necessary code into a text editor and save it as HTML. You can now open the HTML document in your favorite browser and start using your computer. Just like that, you not only can do math in the browser, but also learn the basics of programming arts too!

Steps

Part 1 of 4: Understand your code

1. 

   Learn the functions of each html. The code you use to build your computer is composed of many syntax fragments. They combine to create many different elements of the document. Click here to learn how to familiarize yourself with the process, or read on to see what each line of text does in the code you will use.
   • html: This portion of the syntax tells the rest of the document what the language is to be used. In programming there are many languages ​​used and let the rest of the document know it's written with - that's correct - html!
   • head: Tell the document that the content below is the data about the data, also known as "metadata" (metadata). Comeinand often used to define a stylistic element of the document, such as headings, headings, etc. It can be thought of as an umbrella covering the rest of the code.
   • title: This is where you will name your document. This attribute determines the title of the document when opened in the html browser.
   • body bgcolor = "#": This attribute specifies the background and body color of the code. The number in quotation marks, after the # sign corresponds to a specified color in the html
   • text = "": The word enclosed in quotation marks specifies the text color in the document.
   • form name = "": This attribute specifies the name of the form. Thanks to it, Javascript will identify what the form in question is and apply the structure built up from the form. Here, for example, we use the Calculator form and it will create a separate structure for the document.
   • input type = "": This is where the action takes place. The "input type" property tells the document what type of input the values ​​in the rest of the brackets are in. It could be text, passwords, buttons (for computers), etc.
   • value = "": This command tells the document what the content is contained in the input type specified above. With a calculator, that would be the digits (1-9) and math (+, -, *, /, =).
   • onClick = "": This syntax describes an event - tells the document something happens when someone presses a button. With a computer, we want each button pressed to be displayed. For example, with "6" button, we will put document.calculator.ans.value + = '6' between quotes.
   • br: This tag helps you to return a line in the document. Any content that follows it will appear on the line below the content before it.
   • / form, / body, and / html: these commands tell the document at this point, the corresponding commands initialized will terminate.
