CSS Read-Only Text Box

In web development, the text box is one of the common web page elements. Usually we use text boxes to allow users to enter information such as text or numbers. But sometimes we need to display some information in the text box without allowing users to edit or modify it. At this time, you can use the read-only text box.

The read-only text box is a special text box. The difference from an ordinary text box is that the user cannot edit or modify the content. Read-only text boxes are suitable for non-interactive information display, such as displaying some static text information or data.

Styleing a read-only text box can be easily implemented in CSS. Just add the "readonly" attribute to the text box and style the "readonly" state of the text box in a CSS stylesheet. The following is a simple example of implementing a read-only text box:

<input type="text" value="只读文本框" readonly>

In the above example, we added the "readonly" attribute to a text box, which means that the text box is read-only. In addition, we can style this text box through CSS style sheets to achieve specific visual effects. As shown below:

input[type="text"][readonly]{
  border: none;
  background-color: rgba(0, 0, 0, 0);
  color: #333;
  font-size: 16px;
  font-weight: bold;
}

In the above example, we have used some CSS properties to style the read-only text box. First, we set the border of the text box to None, which means that the text box does not have any strokes. Next we set the background color of the text box to completely transparent. Finally, we set the color and font size of the text in the text box, as well as the boldness of the font. These properties can be adjusted as needed to achieve the desired effect.

In addition, the read-only text box can also be implemented through the "disabled" attribute in the HTML element. However, the text box under the "disabled" attribute cannot submit the form, which means that any information in the text box will not be submitted to the server. Therefore, if we need to let the user view rather than edit or modify specific information, then a read-only text box is a better choice.

In general, read-only text boxes are a useful web development tool that can help us display non-interactive information to users. Through simple CSS settings, we can easily customize the style to adapt to specific interface design requirements.
