In web design, image hiding is a very common technique. Hiding pictures can make web pages more beautiful and tidy, and can also reduce the loading time of web pages and improve users' access experience. Currently, using CSS style sheets to hide images has become one of the standard technologies in web design. In this article, we'll show you how to hide images using CSS stylesheets.
First of all, we need to understand what a CSS style sheet is. CSS is the abbreviation of Cascading Style Sheets, and its Chinese name is Cascading Style Sheets. CSS style sheets are used to control the style and layout of web pages, including fonts, colors, layout, images, and more. To use CSS style sheets to hide images, you need to use the display property and visibility property of CSS.
(1) Use display:none to hide images
display:none is one of the most commonly used attributes for hiding elements in CSS style sheets. When we set the display property of an element to none, the element will not be displayed. Here is a simple example:
HTML code:
CSS code:
img { display: none; }
In the above code, we set the display attribute of all img tags to none . In this way, all images on the web page will be hidden. When we need to display an image, we only need to change the display attribute value of the img tag to block or inline-block to display it.
(2) Use visibility:hidden to hide images
Unlike display:none, visibility:hidden can hide elements, but the elements still occupy the space of the web page. Elements with visibility:hidden will still maintain a space on the page, but will no longer be displayed. Here is a simple example:
HTML code:
CSS code:
img { visibility: hidden; }
In the above code, we set the visibility attribute of all img tags to hidden . In this way, all images in the web page will be hidden, but they will still occupy the original space. When we need to display an image, we only need to change the visibility attribute value of the img tag to visible to display it.
Summary
In web design, image hiding is a very common technique. Using CSS stylesheets to hide images is one of the most common methods. We can hide images entirely with the display:none attribute, or we can hide images but retain their space with the visibility:hidden attribute. By using these attributes, we can reduce the loading time of the web page, improve the user's access experience, and also make the web page more beautiful and tidy.
