CSS to achieve solid arrow
CSS Solid Arrows
In web design, arrows are common graphic elements, often used to indicate a direction or as button styles. In this article, we’ll show you how to create a solid arrow using CSS.
How it works
The key to creating a solid arrow is using the CSS border property to draw a triangle. We can achieve the arrow effect by setting an element’s border style to a small, opaque triangle with the border-color and then placing it in a container with the same background color as the border-color.
Solid Arrow Style
First, we create an HTML element to represent the arrow and set its style as follows:
<div class="arrow"></div>
Next, we use CSS to define the arrow’s style. The implementation code for a solid arrow is as follows:
.arrow {
width: 0;
height: 0;
border-left: 20px solid transparent;
border-right: 20px solid transparent;
border-bottom: 20px solid #000;
}
In this CSS code, we set an element with a width and height of 0, then use the border property to define a small triangle with transparent left and right borders and a black bottom border, creating a solid arrow shape.
Running Results
With the above code, we can display a simple solid arrow style on the page. The sample code is as follows:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Solid Arrow</title>
<style>
.arrow {
width: 0;
height: 0;
border-left: 20px solid transparent;
border-right: 20px solid transparent;
border-bottom: 20px solid #000;
}
</style>
</head>
<body>
<div class="arrow"></div>
</body>
</html>
Opening this code in a browser, we can see a simple black solid arrow.
Summary
Using the CSS border property, we can easily create a solid arrow style. This method does not require additional image resources and can adapt well to various sizes and styles. In actual projects, we can adjust the size and color of the arrow according to specific needs to achieve a personalized arrow style.
