css forbidden icon

May 29, 2023 am 11:16 AM

In front-end development, it is often necessary to use icons to beautify website pages and enhance user experience, but sometimes we may also need to prohibit the appearance of certain icons. At this time, you need to use CSS to implement the function of disabling the icon.

Generally, the way we refer to icons on the page is to use font icons or SVG icons, because they are all vector icons and will not be distorted in different sizes. There are two main ways to disable icons: one is to use pseudo-class selectors in CSS, and the other is to use the data attribute in HTML. Below we will explain the specific implementation of these two methods in detail.

First, let’s look at the first method – using CSS pseudo-class selectors. This method is suitable for use with font icons. Generally, the way we use font icons is by setting the class attribute of the element to the class name of the icon, then using @font-face to declare the font in CSS, introducing the font file into the page, and setting the font-family attribute of the element to This font name is used to display the icon on the page. If we want to prevent an icon from appearing, we can use the :before or :after pseudo-class to replace the original icon class name, and set the content attribute to empty.

For example, we have an element with the class attribute "icon" and an icon class named "icon-delete". If we want to prevent the icon from appearing in the element, we can use it in CSS Write like this:

.icon::before {
  content: none;
}

This will disable the "icon-delete" icon in this element from appearing.

Another way is to use the data attribute in HTML. This method is suitable for use with SVG icons. When using SVG icons, we usually introduce the SVG icon file into the page, and then embed it into HTML using the tag, so that the SVG icon can be displayed on the page. The way to use the data attribute is to set the data attribute in the tag, and store the content of the SVG icon file in the data attribute in the form of Base64 encoding, thereby realizing the function of calling the SVG icon. If you want to disable the appearance of a certain SVG icon, just set the data attribute to empty in the tag.

For example, we have an tag that references an SVG icon file with the ID "icon-delete". If we want to prohibit the SVG icon from appearing on the page, we can write like this:

<object data="" type="image/svg+xml" id="icon-delete"></object>

In this way, the SVG icon can be prohibited from appearing on the page.

Generally speaking, there are two main ways to ban icons: using pseudo-class selectors in CSS and using data attributes in HTML. The specific method should be chosen based on the actual situation. Different icon types, usage methods, and business needs may affect the choice of method. But no matter which method is used, care should be taken not to affect the style and functionality of other parts while implementing the icon ban function.
