How to set the css image size:
1. Image size settings introduced through the img tag
We can directly Set the width and height in the image tag. It should be noted here that directly setting the width and height values in the HTML img tag does not require html units. The default is PX pixels.
The advantage of setting the height and width in the img tag is intuitive. For inserting pictures into articles, you can use this method to control the height and width of the picture. The disadvantage is that if the picture list is formatted like this, a lot of HTML code will be added, making it inconvenient to modify it uniformly.
css Set img image size syntax:
img{width:150px;height:60px}Here, set the CSS width to 150px, and the css height to 60px. Note that the values of css width and css height in the CSS style have units and must be remembered. Be sure to bring your unit with you when you live.
If we set the style directly on img, this will control the width and height of the image in the entire web page. In order to control the image width and height style within the specified object, we usually add the object CSS name before img.
2. Set the background image size with css:
The background-size attribute specifies the size of the background image.
Grammar:
background-size: length|percentage|cover|contain;
Example:
<!DOCTYPE html>
<html>
<head>
<style>
body
{
background:url(/i/bg_flower.gif);
background-size:63px 100px;
-moz-background-size:63px 100px; /* 老版本的 Firefox */
background-repeat:no-repeat;
padding-top:80px;
}
</style>
</head>
<body>
<p>上面是缩小的背景图片。</p>
<p>原始图片：<img src="/static/imghw/default1.png" data-src="/i/bg_flower.gif" class="lazy" alt="Flowers"></p>
