Code Interpretation

Define dom, the navigation contains an unordered list, a span is embedded in the list item, and the text is written in span Center:

Centered display:

body {
    margin: 0;
    height: 100vh;
    display: flex;
    align-items: center;
    justify-content: center;
    background-color: #333;
}

Hide the guide symbol on the front end of the list item:

nav ul {
    padding: 0;
    list-style-type: none;
}

Set the size and color of the button:

nav li {
    width: 8em;
    height: 2em;
    font-size: 25px;
    color: orange;
}

Set text style, note that the height is 120%, span is higher than its parent's li:

nav li span {
    position: relative;
    box-sizing: border-box;
    width: inherit;
    height: 120%;
    top: -10%;
    background-color: #333;
    border: 2px solid;
    font-family: sans-serif;
    text-transform: capitalize;
    display: flex;
    align-items: center;
    justify-content: center;
}

willspan Move the element slightly to the right:

nav li span {
    transform: translateX(4px);
}

Use the left border of the list item li to draw a vertical line:

nav li {
    box-sizing: border-box;
    border-left: 2px solid;
}

Use the left border of the list item The pseudo element draws two more vertical lines, and their heights are reduced in sequence. At this point, there are a total of three vertical lines on the left side of the button:

nav li {
    position: relative;
}

nav li::before,
nav li::after
 {
    content: '';
    position: absolute;
    width: inherit;
    border-left: 2px solid;
    z-index: -1;
}

nav li::before {
    height: 80%;
    top: 10%;
    left: -8px;
}

nav li::after {
    height: 60%;
    top: 20%;
    left: -14px;
}

Gradually darken the color of the two vertical lines of the pseudo element and increase A little layering:

nav li::before {
    filter: brightness(0.8);
}

nav li::after {
    filter: brightness(0.6);
}

Add the mouse hover effect. The default state is that the button covers 3 vertical lines. When the mouse is hovered, the button moves to the right, revealing 3 vertical lines:

nav li:hover span {
    transform: translateX(4px);
}

nav li span {
    /* transform: translateX(4px); */
    transform: translateX(-16px);
    transition: 0.3s;
}

Because the default position of the button is to the left, in order to offset this offset, move the list items slightly to the right:

nav ul {
    transform: translateX(16px);
}

Add a few more buttons to the dom:

Set the spacing of the buttons:

nav li {
    margin-top: 0.8em;
}

You’re done!
