How to hide borders in css

In web design and development, we often need to use borders to beautify the page and distinguish different elements. But sometimes the border is too abrupt and affects the overall beauty of the page. In this case, we need to use CSS to hide the border.

Outline is a CSS property that draws lines around elements. The difference between it and border is that outline does not occupy space and does not affect the appearance of elements. Size and position, so can be used to hide an element's border.

div{
  border: 1px solid black;
  outline: none;
}

2. Use border-color transparent

Another way to hide the border is to use the border-color property and set the value to transparent.

div{
  border: 1px solid transparent;
}

3. Using the border-image property of CSS3

The border-image property of CSS3 allows us to define an image for the border and scale and tile it. This will achieve the effect of hiding the border.

div{
  border-width: 10px;
  border-image: url(border.png) 30 30 round;
}

This code sets the border of the div element to 10 pixels wide, and uses the border-image attribute to set the border to an image named border.png, while scaling and tiling it.
