Images play an important role in any web page. While it’s not recommended to include a lot of images, it’s still important to use good images wherever needed.

CSS plays a great role in controlling image display. You can set the following image properties using CSS.

The border attribute is used to set the width of the image border.

The height attribute is used to set the height of the image.

The width attribute is used to set the width of the image.

The -moz opacity property is used to set the opacity of the image.

1. Image border attribute

The border attribute of the image is used to set the width of the image border. The length or value of this attribute can be %.

Zero pixel width means no border, example:

<html>
   <head>
   </head>
   <body>
      <img  style = "border:0px;" src = "https://img.php.cn/upload/article/000/000/003/5a9675a3b2106284.jpg" / alt="How to use set image effects? (code example)" >
      <br />
      <img  style = "border:3px dashed red;" src = "https://img.php.cn/upload/article/000/000/003/5a9675a3b2106284.jpg" / alt="How to use set image effects? (code example)" >

The width attribute of the image is used to set the width of the image. The length or value of this attribute can be %. Although the value is expressed in %, it applies to the box within which the image is available. The case is as follows:

<html>
   <head>
   </head>
   <body>
      <img  style = "border:1px solid red; height:100px;" src = "https://img.php.cn/upload/article/000/000/003/5a9675a3b2106284.jpg" / alt="How to use set image effects? (code example)" >
      <br />
      <img  style = "border:1px solid red; height:50%;" src = "https://img.php.cn/upload/article/000/000/003/5a9675a3b2106284.jpg" / alt="How to use set image effects? (code example)" >

3.moz-opacity attribute

The -moz-opacity attribute of the image is used to set the opacity of the image. This property is used to create transparent images in Mozilla. IE uses filter:alpha(opacity=x) to create transparent images. [Recommended reading: How to achieve transparency and opacity of images in css]

In Mozilla (-moz-opacity: x) x can be a value between 0.0 and 1.0. Lower values make the element more transparent (CSS3 valid syntax for opacity is the same: x).

In IE (filter: alpha(opacity = x)) x can be a value between 0 and 100. Lower values make the element more transparent. The code is as follows:

<html>
   <head>
   </head>
   <body>
      <img  style = "border:1px solid red; -moz-opacity:0.4; filter:alpha(opacity=40);" src = "https://img.php.cn/upload/article/000/000/003/5a9675a3b2106284.jpg" / alt="How to use set image effects? (code example)" >
   </body>
</html>
