Which one should we use ‘border: none’ or ‘border: 0 ‘?
In CSS, the ‘border’ property is used to add a border to the HTML elements. We can add a border of widths, styles, and colours to the HTML element.
Two border values come to mind when we need to remove the border from any element. The first value is ‘none’, and the second is ‘0’. Sometimes, it creates confusion about which value we should use, and in this tutorial, we will clear that doubt.
Syntax
Users can follow the syntax below to use the ‘none’ or ‘0’ as a value of the ‘border’ property.
border: none; border: 0;
Border: none VS border: 0
Before we start with the examples, let’s look at the difference between the border's ‘none’ and ‘0’ values.
| Border: none | Border : 0 |
|---|---|
| It is a short form for the border-style: none CSS property. | It is a short form for border-width: 0 CSS property. |
| The broder: none hides the border from the element but doesn’t remove the border from the element. | The broder: 0 property removes the border from the element and doesn’t render the broder on the browser. |
| Also, it doesn’t remove the border from the browser and occupies the browser's memory. | It doesn’t occupy the memory of the browser. |
| Never use ‘border: none’ as it affects the application performance. | Always use the broder: 0 to remove the broder from the element. |
Example 1
In the example below, we have created the two different div elements, added content, and given the different class names. For the first div element, we have applied the ‘border: none’ and the second div element border is ‘border: 2px dashed green’.
In the output, users can observe that ‘border: none’ hides the broder from the first div element.
<html>
<head>
<style>
.first {
border: none;
background-color: lightblue;
padding: 20px;
text-align: center;
width: 500px;
}
.second {
border: 2px dashed green;
padding: 10px;
text-align: center;
width: 500px;
margin: 20px;
}
</style>
</head>
<body>
<h3> Using the <i> border: none </i> CSS property to remove border of elements </h3>
<div class = "first"> BMW, Audi </div>
<div class = "second"> Apple, Banana </div>
</body>
</html>
Example 2
In the example below, we created two different div elements like the first example. We have used the ‘border: 0’ CSS property to remove the border from the first div element.
<html>
<head>
<style>
.one {
border: 0;
background-color: yellow;
padding: 20px;
width: 200px;
}
.two {
border: 2px solid red;
padding: 10px;
width: 200px;
margin: 20px;
}
</style>
</head>
<body>
<h3> Using the <i> border: 0 </i> CSS property to remove border of elements. </h3>
<section class = "one"> This is a second with border: 0</section>
<section class = "two"> This is a second with border: 2px solid red</section>
</body>
</html>
Example 3
In the example below, we have used the border: 0, border: none, border-style: none, and border-width: 0 CSS properties with the div elements. Here, we have created four different div elements, added different content, and given different background colours.
Also, we have used different border properties for every div element. In the output, users can observe that all properties remove the border from the div element.
<html>
<head>
<style>
.one {
width: 300px;
margin: 10px;
padding: 10px;
border: 0;
background-color: greenyellow;
}
.two {
width: 300px;
margin: 10px;
padding: 10px;
border-width: 0;
background-color: aqua;
}
.three {
width: 300px;
margin: 10px;
padding: 10px;
border: none;
background-color: yellow;
}
.four {
width: 300px;
margin: 10px;
padding: 10px;
border-style: none;
background-color: brown;
}
</style>
</head>
<body>
<h3> Using the <i> border: 0, border: none, border-style: none, and border-width: 0 </i> CSS property to remove border of elements </h2>
<section class = "one"> border: 0 </section>
<section class = "two"> border-width: 0 </section>
<section class = "three"> border: none </section>
<section class = "four"> border-style: none </section>
</body>
</html>
From the above tutorial, we can conclude that users should use the ‘border: 0’ or ‘border-width: 0’ instead of using the ‘border: none as it removes the border-style from the element, but the border still exists. Using the ‘border: 0’ also improves the application performance at some level. However, we can’t see the difference for small applications, but at large scale, it affects.
