I had shared my HTML Form study notes, and it is time to use those key elements to do a small form project. The Udemy course assignment is creating a register form like below: There are a few requirements: First name, Last name, Email are required fields Password requires 5 to 10 characters Three drop-down contents: Month, Day and Year Three radio buttons: Male, Female and Other One checkbox Let's Start! Step One: Use <label> and <input> to create First Name and Last Name fields Before I create form, I start to enter page title "Register Form", and put header as "Register" under <body> tag. So when I open the page on browser, I can see the page is about "Register Form". Then, I begin to create the form by enter <form> tag. The web application will know there will be a form under the page header. If you want to submit this form to another page, you need to add "action" and "method"...
