CSS Navigation Bar: Main Tips
- Navbar in CSS refers to a group of links that lead to different pages of a web site.
- Navbars are either vertical or horizontal.
- The <nav> element should wrap primary bars such as the main navigation links of web sites.
Defining Navbars
A CSS navigation bar is a collection of links. This example shows a functional and styled navigation bar:
Example
                              ul                {                border:                2px                solid                #e7e7e8;                background-color:                #e7e7e8; }                li                a                {                color: white; }                      HTML creates the base of a navbar with two elements:
- <li> (defines an item of a list)
- <ul> (defines an unordered list)
- Ordered
- list
- Unordered
- list
In these examples, HTML list elements create the functional part of navbars:
- Link1
- Link2
- Link3
- Link4
Example
                              <ul>                <li>                <a                  href="https://www.bitdegree.org/"                  target="_blank">Link1</a>                </li>                <li>                <a                  href="https://www.bitdegree.org/"                  target="_blank">Link2</a>                </li>                <li>                <a                  href="https://www.bitdegree.org/"                  target="_blank">Link3</a>                </li>                <li>                <a                  href="https://www.bitdegree.org/"                  target="_blank">Link4</a>                </li>                </ul>                                    It is necessary to remove the browser default settings for navbars:
-             list-style-type: noneremoves the bullets from CSS navigation bars.
-             margin: 0;andpadding: 0;removes the browser default spacing settings.
- These properties are for both horizontal and vertical navigation bars.
In the example, we remove padding, margins, and the bullets from the list:
Example
                              ul                {                list-style-type: none;                margin:                0;                padding:                0; }                      <nav> Element
The <nav> element indicates that a group of links are for navigation. However, placing the ordered or unordered lists in this element is not a requirement.
Tip: you should place your navigation bar in <nav> for major bars.
Vertical Navigation Bar
The vertical navigation bar appears as a regular list of links. The vertical bar is useful for web navigation and can easily become a dropdown menu.
- Link1
- Link2
- Link3
- Link4
Example
                              li                a                {                display: block;                width:                50px;                color: purple;                background-color: cornsilk;                text-decoration: none; }                li                a                :hover                {                background-color:aliceblue; }                                    Here are some points about the example above:
- Remember to remove the default browser styles (margin, padding, bullet points).
- Add            text-decoration: none;to remove the underline.
- Add various properties to customize the CSS vertical navigation bar.
- The            :hoverselector indicates that when the mouse cursor moves over a link in the CSS navbar, the background color changes.
Ways to Style Vertical Navbars
Styling properties can make CSS navigation bars match various web designs. You can experiment by adding different background colors, changing the font family or the text alignment.
This example creates a vertical navigation bar. However, styling properties          change          when          :hover          triggers:
Example
                              ul                {                list-style-type: none;                margin:                0;                padding:                0;                width:                250px;                background-color:                #8842d5; }                li                a                {                display: block;                color: white;                padding:                9px                17px;                text-decoration: none; }                /* When the link is hovered on, its color will change */                li                a                :hover                {                background-color:                #7300ff;                color: black; }                                    Active Navigation Links
You can add styles to a CSS navigation bar when users click on one of the links. You should use the :active selector to indicate the state for which the new styling rules should apply:
Example
                              .active                {                background-color:                #7300ff;                color: black; }                                    Centering Links & Adding Borders
- Link1
- Link2
- Link3
- Link4
The text inside the CSS navigation bar appears on the          left          side by default. You can easily change this rule by adding          text-align:center          to make sure that all links appear at the          center          of the navbar.
Note: set text-align property to left or right to move the text to those directions.
It is possible to separate the CSS navigation menu from the rest of the website by adding borders.
This example adds borders and centers the text:
Example
                              ul                {                border:                2px                solid black; }                li                {                text-align: center;                border-bottom:                1px                solid                rgb(0, 0, 0); }                li                :last-child                {                border-bottom: none; }                                    Fixed Height of a Vertical Navbar
You can set the CSS navigation bar to be on the specified side and continue until the end of the page:
- Set the height to 100%.
- Indicate the            permanent position            with            fixed.
- Add            overflow: autoto insert a scrollbar to the navigation bar.
Example
                              ul                {                list-style-type: none;                margin:                0;                padding:                0;                width:                30%;                background-color:                #8842d5;                height:                100%;                /* This enables full height */                position: fixed;                /* The position will be constant */                overflow: auto;                /* This enables scrolling */                }

Horizontal Navigation Bar
- Link1
- Link2
- Link3
- Link4
CSS creates horizontal navigation bars by:
- Assigning            display: inlineproperty to a list of links.
- Using float.
Inline List Items
CSS builds a          horizontal CSS navbar          with the          display:inline          property assigned to          <li>          elements.
Tip: <li> elements are block elements by default. The inline value displays links a row instead of new lines.
Floating List Items
The second way of creating a horizontal navbar is the          float          property. It sets the layout for navigation links by floating the          <li>          elements.        
The          float          property can use          two          keywords:          left          or          right.        
In the example below, we create a CSS navigation bar by using          float: right:
Example
                              li                {                float: right; }                a                {                display: block;                padding:                9px;                background-color:                #8842d5; }                      In the example, one of the links moves to the right with the          float:right:
- Link1
- Link2
- Link3
- Link4
Example
                              <ul>                <li>                <a                  href="https://www.bitdegree.org/"                  target="_blank">Link1</a>                </li>                <li>                <a                  href="https://www.bitdegree.org/"                  target="_blank">Link2</a>                </li>                <li>                <a                  href="https://www.bitdegree.org/"                  target="_blank">Link3</a>                </li>                <li                  style="float: right;">                <a                  class="active"                  href="https://www.bitdegree.org/"                  target="_blank">Link4</a>                </li>                </ul>                                    Hovering Over Horizontal Navigation Bar
This example          adds          :hover          to the horizontal navigation bar in order to change the background color when cursors enter it:
Example
                              ul                {                list-style-type: none;                margin:                1px;                padding:                1px;                overflow: hidden;                background-color:                #8842d5; }                li                {                float: left; }                li                a                {                display: block;                color: white;                text-align: left;                padding:                15px                17px;                text-decoration: none; }                /* A color changes when hovered over */                li                a                :hover                {                background-color:                #7300ff; }                      Active Navigation Links
This example adds the          :active          selector to          change the styling          of the link when users click on it:
Example
                              li                a                .active                {                background-color:                #7300ff; }                      Adding Borders
CSS borders add a visible separation between the navbar and the rest of the content.
Example
                              /* All items except the last one will have a border on the right side */                li                {                border-right:                2px                solid white; }                li                :last-child                {                border-right: none; }                      Fixed Position
You can make the CSS navigation bar permanently stay at the bottom or the top of the page regardless of scrolling.
          position: fixed          and          top: 0          create the navigation bars that are fixed at the top:
Example
                              ul                {                position: fixed;                top:                0;                width:                100%; }                                position: fixed          and          bottom: 0          create navigation bars that are fixed at the bottom:
Example
                              ul                {                position: fixed;                bottom:                0;                width:                100%; }                      CSS Navigation Bar: Useful Tips
