HTML text box is a commonly used form element, which allows users to enter text information on web pages, such as registration forms, message boards, etc. If you want to know how to set up an HTML text box, this article will provide you with a detailed introduction and operation guide.
First, we need to understand the basic syntax and properties of HTML text boxes. In HTML, a text box can be created using the following code:
<input type="text" name="inputbox" id="inputbox" placeholder="请输入内容" />
The above code defines a text box, where type="text" indicates that this is a text box, name is the name of the element in the form, id is the unique identifier of the element, and placeholder is the placeholder text displayed in the text box.
Next, we can use CSS styles to beautify the text box, for example:
input[type="text"] {
padding: 10px;
border: 1px solid #ccc;
border-radius: 5px;
font-size: 16px;
}
The above code will add styles to all type elements that are text boxes. Among them, padding represents the inner margin of the text box, border represents the border of the text box, border-radius represents the rounded corners of the text box, font -size indicates the font size of the text box text.
In addition to the above basic attributes, the text box also has the following common attributes:
-
size: The width of the text box, calculated in terms of the number of characters; -
maxlength: The maximum number of characters entered in the text box; -
readonly: The text box is read-only and cannot be entered; -
disabled: The text box is disabled and no operations can be performed.
For example, the following code will create a text box with a width of 30 characters and limit the number of input characters to 20:
<input type="text" name="inputbox" id="inputbox" size="30" maxlength="20" />
If you need to set up a multi-line text box, just The type attribute needs to be set to textarea, as shown below:
<textarea name="textarea" id="textarea" rows="5" cols="30"></textarea>
The above code will create a text box with 5 rows and 30 columns.
In addition to the above common properties, the text box has many other properties and events, you can make reasonable choices according to your needs.
To sum up, the setting of HTML text box is very flexible and diverse. You can use different attributes and styles according to your needs to present the effect you want. Hope this article can be helpful to you!
