Use jQuery's toggle() method to display and hide HTML tags
Here is an example:
<span style="color: #0000ff;"><</span><span style="color: #800000;">html</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"><</span><span style="color: #800000;">head</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"><</span><span style="color: #800000;">script </span><span style="color: #ff0000;">type</span><span style="color: #0000ff;">="text/javascript"</span><span style="color: #ff0000;"> src</span><span style="color: #0000ff;">="https://code.jquery.com/jquery-1.11.3.js"</span><span style="color: #0000ff;">></</span><span style="color: #800000;">script</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"><</span><span style="color: #800000;">script </span><span style="color: #ff0000;">type</span><span style="color: #0000ff;">="text/javascript"</span><span style="color: #0000ff;">></span><span style="background-color: #f5f5f5;

The toggle() method used in the example:
The toggle() method switches the visible state of the element. If the selected elements are visible, then hide these elements. If the selected elements are hidden, then show these elements. Syntax$(selector).toggle(speed,callback,switch)
Parameters |
Description |
speed |
Optional. Specifies how quickly an element goes from visible to hidden (or vice versa). Default is "0". Possible values:
When setting the speed, the element will gradually change its height, width, margin, padding and transparency as it goes from visible to hidden. If this parameter is set, the switch parameter cannot be used. |
callback |
Optional. toggle The function to be executed after the function is executed. To learn more about callbacks, visit our jQuery Callback chapter. This parameter cannot be set unless the speed parameter is set. |
switch |
Optional. Boolean value. Specifies whether toggle hides or shows all selected elements.
If this parameter is set, the speed and callback parameters cannot be used. |
PS: This effect applies to elements hidden through jQuery, or elements declared display:none in CSS (but not elements with visibility:hidden).
