In web design, the text box is a commonly used element that allows users to enter information on the page. This article will introduce how to set up text boxes in HTML.

  1. Using the tag

To create a text box, use the tag and set its type to "text". Here is a basic example: 

<input type="text" name="username">
Copy after login

In this example, we create a text box and name it "username".

You can use the "size" attribute to set the size of the text box, for example:

Copy after login

In this example , we set the size of the text box to 30 characters wide.

Copy after login

In this example, we set the maximum length of the text box to 20 characters.

Copy after login

In this example , we set the default value of the text box to "Please enter the user name".
