Position

Position - Bootstrap 5 & Material Design 2.0

Use these helpers for quickly configuring the position of an element.


Basic examples

Fixed top

Position an element at the top of the viewport, from edge to edge. Be sure you understand the ramifications of fixed position in your project; you may need to add additional CSS.


          <div class="fixed-top">...</div>
        

Fixed bottom

Position an element at the bottom of the viewport, from edge to edge. Be sure you understand the ramifications of fixed position in your project; you may need to add additional CSS.


          <div class="fixed-bottom">...</div>
        

Sticky top

Position an element at the top of the viewport, from edge to edge, but only after you scroll past it. The .sticky-top utility uses CSS’s position: sticky, which isn’t fully supported in all browsers.


          <div class="sticky-top">...</div>
        

Responsive sticky top

Responsive variations also exist for .sticky-top utility.


          <div class="sticky-sm-top">Stick to the top on viewports sized SM (small) or wider</div>
          <div class="sticky-md-top">Stick to the top on viewports sized MD (medium) or wider</div>
          <div class="sticky-lg-top">Stick to the top on viewports sized LG (large) or wider</div>
          <div class="sticky-xl-top">
            Stick to the top on viewports sized XL (extra-large) or wider
          </div>
        

Position values

Quick positioning classes are available, though they are not responsive.


          <div class="position-static">...</div>
          <div class="position-relative">...</div>
          <div class="position-absolute">...</div>
          <div class="position-fixed">...</div>
          <div class="position-sticky">...</div>
        

Arrange elements

Arrange elements easily with the edge positioning utilities. The format is {property}-{position}.

Where property is one of:

  • top - for the vertical top position
  • left - for the horizontal left position
  • bottom - for the vertical bottom position
  • right - for the horizontal right position

Where position is one of:

  • 0 - for 0 edge position
  • 50 - for 50% edge position
  • 100 - for 100% edge position

You can add more position values by adding entries to the $position-values Sass map variable.


          <div class="position-relative position-relative-example">
            <div class="position-absolute top-0 left-0"></div>
            <div class="position-absolute top-0 right-0"></div>
            <div class="position-absolute top-50 left-50"></div>
            <div class="position-absolute bottom-50 right-50"></div>
            <div class="position-absolute bottom-0 left-0"></div>
            <div class="position-absolute bottom-0 right-0"></div>
          </div>
        

          .position-relative-example { height: 200px; width: 100%; background-color: #f5f5f5; }
          .position-relative-example div { width: 2em; height: 2em; background-color: #343a40;
          border-radius: .25rem; }
        

Center elements

In addition, you can also center the elements with the transform utility class .translate-middle.

This class applies the transformations translateX(-50%) and translateY(-50%) to the element which, in combination with the edge positioning utilities, allows you to absolute center an element.


          <div class="position-relative position-relative-example">
            <div class="position-absolute top-0 left-0 translate-middle"></div>
            <div class="position-absolute top-0 left-50 translate-middle"></div>
            <div class="position-absolute top-0 left-100 translate-middle"></div>
            <div class="position-absolute top-50 left-0 translate-middle"></div>
            <div class="position-absolute top-50 left-50 translate-middle"></div>
            <div class="position-absolute top-50 left-100 translate-middle"></div>
            <div class="position-absolute top-100 left-0 translate-middle"></div>
            <div class="position-absolute top-100 left-50 translate-middle"></div>
            <div class="position-absolute top-100 left-100 translate-middle"></div>
          </div>
        

          .position-relative-example { height: 200px; width: 100%; background-color: #f5f5f5; }
          .position-relative-example div { width: 2em; height: 2em; background-color: #343a40;
          border-radius: .25rem; }
        

Additional examples

Here are some real life examples of these classes:


          <button
            type="button"
            class="btn btn-primary position-relative"
            data-ripple-unbound="true"
          >
            Mails
            <span
              class="position-absolute top-0 left-100 translate-middle badge rounded-pill bg-secondary"
              >+99 <span class="visually-hidden">unread messages</span></span
            >
          </button>

          <button type="button" class="btn btn-dark position-relative" data-ripple-unbound="true">
            Marker
            <svg
              width="1em"
              height="1em"
              viewBox="0 0 16 16"
              class="position-absolute top-100 left-50 translate-middle bi bi-caret-down-fill"
              fill="#343a40"
              xmlns="http://www.w3.org/2000/svg"
            >
              <path

              />
            </svg>
          </button>

          <button
            type="button"
            class="btn btn-primary position-relative"
            data-ripple-unbound="true"
          >
            Alerts
            <span
              class="position-absolute top-0 left-100 translate-middle badge border border-light rounded-circle bg-danger p-2"
              ><span class="visually-hidden">unread messages</span></span
            >
          </button>
        

You can use these classes with existing components to create new ones. Remember that you can extend its functionality by adding entries to the $position-values variable.
