When I write a web page with a menu bar, I basically use responsive design to adapt to the mobile terminal, such as hiding unimportant menu options, or creating a menu button to control the opening and closing of the menu. some type of. I have always

used JavaScript to open and close the menu, but recently I saw someone using CSS and HTML to implement this function on the Internet, which made me really feel that as long as I have a hammer in my hand, , anything can be made into nails.

Before implementing, let’s take a look at the

HTML label and input type:

label

The label is input Element definition annotation (tag). The

label element does not present any special effects to the user. However, it improves usability for mouse users. This control is triggered if you click on the text inside the label element. That is to say, when the user selects the label, the browser will automatically turn the focus to the form control related to the label.

The for attribute of the label should be the same as the id attribute of the related element.

Input Type: checkbox

Define the checkbox.

Checkboxes allow the user to select zero or more options from a limited number of options.

The following is the demo code:

<!DOCTYPE html>
