Aligning Common Elements to the Bottom with a Simple CSS Technique

For Example:

To position a button at the bottom of each column and make them appear on the same line, you can use CSS flexbox or CSS grid, depending on your layout structure. Here are examples using both approaches:

HTML

<div class="container">
  <div class="column">
    <!-- Column content -->
    <button class="bottom-button">Button</button>
  </div>
  <div class="column">
    <!-- Column content -->
    <button class="bottom-button">Button</button>
  </div>
  <div class="column">
    <!-- Column content -->
    <button class="bottom-button">Button</button>
  </div>
</div>

CSS

.container {
  display: flex;
  flex-direction: row;
}


.column {
  flex: 1;
  display: flex;
  flex-direction: column;
}


.bottom-button {
  margin-top: auto;
}

In this example, the margin-top: auto; on the button will push it to the bottom of each column, and the display: flex; on the .column class ensures that the columns are displayed in a row.

This method can be used without setting a predefined height for a column or a section.
