CSS3 Hide Show

CSS3 is the latest CSS standard, which provides us with more style choices and controls, one of which is the control of hiding and showing elements. In this article, we will talk about how to hide and show elements using CSS3 and where this technique can be beneficial.

There are four display properties in CSS3: none, block, inline and inline-block. The most commonly used ones are none and block. none means to completely hide the element, and block means to display the element in a block on the screen.

To achieve a hiding and showing effect, we need to use these display properties in combination with some other properties in CSS3. Here are some properties that will allow you to better achieve these effects:

display:none: Hides the element completely. When an element is set to this property, it will not render on the page.

display:block: Let the element be displayed on the screen in a block shape. This property is typically used to make hidden elements reappear on the screen.

visibility:hidden: Hide the element, but the space it occupies still exists. This attribute is usually used when the original layout needs to be maintained to avoid page layout problems.

visibility:visible: Make the element visible. This property makes the element visible again after hiding it.

opacity:0: Make the element transparent, thus hiding the element. This property is typically used when smoothing/fading effects are required.

opacity:1: Resets the transparency to normal value (1) so that the element can be seen again and other elements can be displayed normally.

transition:all 0.5s ease: Set the transition time of the style attribute change to half a second (0.5s), and set its transition effect to "ease". This property is commonly used to create smooth CSS transition effects.

Next we will use examples to demonstrate how to use the above properties to achieve hiding and display effects.

First, we use the display:none attribute to completely hide an element, as shown below:

.hide-me{
    display:none;
}

This will hide elements with class "hide-me".

We can then use display:block or display:inline-block to restore the display of that element as follows:

.show-me{
    display:block;
}

This will remove the element with class "show-me" Set as a block-level element and bring it back on screen.

Next, we can use visibility:hidden to hide the element, but the space it occupies still exists, as shown below:

.hide-me{
    visibility:hidden;
}

This will hide the element with class "hide-me" element and still occupy the same space in the page layout.

We can then use visibility:visible to end hiding the element and make it re-show, like this:

.show-me{
    visibility:visible;
}

This will make the element with class "show-me" re-show displayed on the page.

If you need a smoother transition effect, you can use the opacity attribute like this:

.hide-me{
    opacity:0;
    transition:all 0.5s ease;
}

This will set the element with class "hide-me" to transparent, and Set the transition time of the style change to half a second (0.5s), and set the transition effect to "ease".

Finally, you can use opacity:1 and transition:all 0.5s ease to end hiding and show the element to the user, like this:

.show-me{
    opacity:1;
    transition:all 0.5s ease;
}

This will make the element with class "show- me" element is opaque and smoothly fades out in half a second.

Summary:

CSS3 provides a series of properties that allow us to better control the hiding and display effects of elements. Different attributes generally correspond to different application scenarios, which can involve aspects such as Web design, visual effects design, and user experience design. While making our website or UI more interactive and visual, the effect of hiding/showing elements can optimize the design capabilities of most of our products and services.
