Ways to hide a sidebar on smaller displays?

I've been attempting to create a collapsible fixed sidebar, but I'm facing some challenges. Despite searching online for solutions, I haven't been able to find any that work.

Here is the code snippet from my sidebar.html:

<div class="container-fluid" style="background-color:#19334d">
<div class="sidebar" id="sidebar">
    <div class="pt-5 text-center pb-2 ">
        <a href="../index.php" class="logo-normal pr-3">
            <img src='../assets/img/favicon.ico' width="50px">
        </a>
        <a href="../index.php" class="logo-normal">
            Fitness Addict 
        </a>
    </div>
    <hr style="border-color:white; width:90%" align=center>
    <ul class="nav pl-4">
        <li >
            <a href="../home/myhome.php">
                <i class="fa fa-home icon pr-4"></i>
                My Home
            </a>
        </li>                
        .
        .
        .
    </ul>
</div>

Below is the CSS used in styling the sidebar:

.sidebar{
  height: calc(100vh - 90px);
  width: 230px;
  position: fixed;
  top: 0;
  left: 0;
  z-index: 1;
  background-size: cover;
  background-position: center center;
  display: block;
  background: #408000;
  box-shadow: 0px 0px 45px 0px rgba(0, 0, 0, 0.6);
  margin-top: 80px;
  margin-left: 20px;
  border-radius: 5px;
}

.sidebar .nav {
 margin-top: 20px;
 display: block;
}

I've attempted using JavaScript to achieve the collapsing effect, but I'm struggling with it. If anyone has any suggestions or can offer assistance, please let me know!https://i.sstatic.net/Yck5u.png

Answer №1

If you want to implement a collapsible sidebar in your website, your JavaScript code could resemble the following:

/* Function to open the sidebar by setting its width to 250px and adjusting the left margin of the main content */

function openNav() 
{
document.getElementById("sidebar").style.width = "250px";
document.getElementById("main").style.marginLeft = "250px";
}

/* Function to close the sidebar by resetting its width to 0 and the main content's left margin to 0 */

function closeNav() 
{
document.getElementById("sidebar").style.width = "0";
document.getElementById("main").style.marginLeft = "0";
}

To incorporate this JavaScript functionality into your HTML file, make sure to refer to W3Schools' tutorial for guidance.

For a more comprehensive guide on creating a responsive sidebar, take a look at the informative tutorial available on W3Schools.

Answer №2

Hidden:

display: none;

Visible:

display: block;

Answer №3

try adjusting the sidebar properties

.sidebar{
    transform:translateX(-100%);
}

activate the sidebar by adding the 'active' class using JavaScript and apply CSS styling

.sidebar.active{
    transform:translateX(0%);
}

Apply a property to the parent element of the sidebar

.parent{
    overflow-x:hidden;
}

Answer №4

not hidden:

.sidebar {
    transition: left 0.3s ease-out;
}

hidden by adding class 'invisible' :

.sidebar.invisible {
    left: -295px;
}

-295px is calculated based on the sidebar's width of 230px, margin-left of 20px, and box-shadow with a blur of 45px

Answer №5

To achieve a sliding effect, you can utilize CSS along with the transition property.

In your CSS file:

.sidebar {
  // Insert your existing code here
  left: -210px; // For example purposes
  transition: left 2s ease;
}

.sidebar:hover{
  left: 0px;
}

By implementing this code, your div will smoothly slide in over a period of 2 seconds and disappear upon no longer being hovered.

Answer №6

If you're looking to create responsive websites that work seamlessly on all devices, consider giving Bootstrap a try! It's designed to make the process easy and offers a variety of other exciting features as well. Take a look at their documentation

Answer №7

One way to optimize your sidebar for different screen sizes is by using media queries:

.sidebar{
  height: calc(100vh - 90px);
  width: 230px;
  position: fixed;
  top: 0;
  left: 0;
  z-index: 1;
  background-size: cover;
  background-position: center center;
  display: block;
  background: #408000;
  box-shadow: 0px 0px 45px 0px rgba(0, 0, 0, 0.6);
  margin-top: 80px;
  margin-left: 20px;
  border-radius: 5px;
}

.sidebar .nav {
 margin-top: 20px;
 display: block;
}

@media (max-width: 400px) {
  .sidebar {
    display: none;
  }
}
<div class="container-fluid" style="background-color:#19334d">
<div class="sidebar" id="sidebar">
    <div class="pt-5 text-center pb-2 ">
        <a href="../index.php" class="logo-normal pr-3">
            <img src='../assets/img/favicon.ico' width="50px">
        </a>
        <a href="../index.php" class="logo-normal">
            Fitness Addict 
        </a>
    </div>
    <hr style="border-color:white; width:90%" align=center>
    <ul class="nav pl-4">
        <li >
            <a href="../home/myhome.php">
                <i class="fa fa-home icon pr-4"></i>
                My Home
            </a>
        </li>                
    </ul>
</div>
