CSS Input Number Rewrite Style

In the process of web development, <input> is often used. Tags are used to create form elements, including <input type="number"> for entering numbers. By default, browsers render <input type="number"> according to the user agent style sheet, but we can customize its appearance through CSS styles. This article details how to rewrite the style of <input type="number> using CSS.

1. Basic Styling Ideas

When rewriting the style of <input type="number>, we mainly need to consider the following aspects:

Input box width and height
Input box border style and color
Input box internal style (such as text color, alignment, etc.)
Input box mouseover effect

Below, we’ll explain how to achieve each of the above effects using CSS.

2. Width and Height

First, we can adjust the width and height of the input box by setting the width and height properties. For example, we can set the width to 200px and the height to 30px:

input[type=number] {
width: 200px;
height: 30px;
}

3. Border Style and Color

Next, we can define the border style and color of the input box by setting the border property. For example, we can set the border to a solid red line:

input[type=number] {
border: 1px solid red;
}

4. Input Internal Styles

We can also define the text color by setting the color property and the text alignment by setting the text-align property. For example, we can set the text color to blue and the text alignment to right:

input[type=number] {
color: blue;
text-align: right;
}

5. Mouseover Effects

Finally, we can define the mouseover effect by setting the :hover pseudo-class. For example, we can set the background color to gray:

input[type=number]:hover {
background-color: lightgray; 
}

6. Complete Example

Here is a complete example demonstrating how to style <input type="number"> using CSS:

<!DOCTYPE html> 
<html> 
<head> 
<style> 
input[type=number] { 
width: 200px; 
height: 30px; 
border: 1px solid red; 
color: blue; 
text-align: right; 
} 

input[type=number]:hover { 
background-color: lightgray; 
} 
</style> 
</head> 
<body> 

<input type="number"> 

</body> 
</html>

In the example above, we define the width of the <input type="number> as 200px and the height as 100px. 30px, solid red border, blue text, right-aligned. When you hover over the input box, the background changes to gray.

With the above style settings, we can customize the style of <input type="number> to suit our needs and design style, making it more suitable for our web design.
