Sizing

Easily make an element as wide or as tall with our width and height utilities.

Bootstrap Sizing documentation

Relative to the parent

Width and height utilities are generated from the $sizes Sass map in _utilities.scss. Includes support for 25%, 50%, 75%, 100%, and auto by default. Modify those values as you need to generate different utilities here.

        
          <div class="w-25">Width 25%</div>
          <div class="w-50">Width 50%</div>
          <div class="w-75">Width 75%</div>
          <div class="w-85">Width 85%</div>
          <div class="w-100">Width 100%</div>
          <div class="w-auto">Width auto</div>
        
      
        
          <div class="h-25">Height 25%</div>
          <div class="h-50">Height 50%</div>
          <div class="h-75">Height 75%</div>
          <div class="h-100">Height 100%</div>
          <div class="h-auto">Height auto</div>

You can also use max-width: 100%;, min-height: 100%; and max-height: 100%; utilities as needed.

        
          <div class="mw-100">Max-width: 100%</div>
        
      
        
          <div class="mh-100">Max-height: 100%</div>
        
      
        
          <div class="min-h-100">Min-height: 100%</div>
