To set your div's minimum viewport height to 100% while allowing it to expand and contain dynamic content:

.container {
  min-height: 100vh;  /* Little trick to cover full viewport */
  display: block;     /* Good old block, just can't beat it */
  overflow: auto;     /* Better keep this handy for extra content */
}

This quick fix ensures your div shoes always fit, whether Cinderella's slipper or Hagrid's boots.

Transforming the layout dimension

Extra love for database or user-oriented content warrants a flexible mind and container.

Flexbox: The Stage Magician for layout geometry

The stage, the cube, the dimensions from Professor's Tesseract, or your layout- they are indeed responsive:

.tesseract {
  display: flex;
  min-height: 100vh;
  flex-direction: column; /* The secret scroll parchment from vertical forest */
}

Just like Mary Poppins' bag, the box grows with more of Bert's drawings or your dynamic content.

Floats: Tamed with your own Clearfix Lasso

Ever tried to nail down a floating balloon? A clearfix can help parent div give a bear hug to the floaty children:

.balloon-holder::after {
  content: "";
  display: table;
  clear: both;  /* Because Ghostbuster traps aren't invented yet */
}

Overflow: The anticipatory Janitor

Ever experienced a deluge from a clogged pipe? Similar is the case of exceeding content. Bring your plunger: overflow: hidden; or overflow: auto;.

Tweaking layout for adaptiveness and efficient design

Adapting to different screen sizes and anticipating content flow is vital. Bring out your wizardry for managing this:

Media queries: Your responsive design spells

Cast your media queries spell in your style sheet cauldron for different potions (read: resolutions):

@media (max-width: 800px) {
  .container {
    padding: 10px; /* Pocket-size for Dobby-sized screens */
  }
}

CSS variables: Your potions for streamlined style adaptation

No need to remember all spells (styles). Use bookmarks (CSS variables) in your spell book (style sheet):

:root {
  --main-padding: 20px; /* Because coding without variables is like a wizard without a wand */
}

.container {
  padding: var(--main-padding);
}

Seamless transition: Brings a whimsy to visual adjustment

A change could be a jolt or a waltz. Grace your content adjustment by adding transitions:

.container {
  transition: height 0.5s ease; /* Because smooth transitions are as satisfying as perfect wand flicks */
}

Positioning: The invisible Clock Tower in your layout village

Absolute-positioned elements are like magic clock towers, can be a headache. Make them relative to the parents, fearful of the Time-Turner:

.relative-container {
  position: relative; /* The clock tower's foundation */
}

.absolute-content {
  position: absolute; /* The hovering clock face */
  top: 20px;
  right: 20px;
}
