How Can I Horizontally Align Divs Without Using Tables?

Horizontal Alignment of Divs without Tables

In web design, aligning elements horizontally often arises, especially when presenting content in columns. While tables provide a straightforward solution for this task, their use may not always be desirable. This article addresses the question of aligning div elements horizontally without resorting to tables.

Using Float and Parent Container

The fundamental technique to align divs horizontally involves using the float property. Float causes an element to shift along a specified direction, aligning it with adjacent elements. To achieve horizontal alignment, the following principles can be applied:

1. Create a Parent Container: Wrap the divs in a parent container. This container will provide the context for horizontal alignment.
2. Float the Divs: Set the float property to 'left' for all child divs within the parent container. This will cause the divs to float towards the left.
3. Clear Float: To prevent the parent container from collapsing, apply the 'clear: none;' style to the child divs. This ensures that the height of the parent container is not influenced by the floating child divs.

4. Example Code:

   .aParent div {
    float: left;
    clear: none; 
   }
   
   .aParent {
    /* Add any additional styles for the parent container here */
   }

<div class="aParent">
    <div>
        <span>source list</span>
        <select size="10">
            <option></option>
            <option></option>
            <option></option>
        </select>
    </div>
    <div>
        <span>destination list</span>
        <select size="10">
            <option></option>
            <option></option>
            <option></option>
        </select>
    </div>
</div>

By implementing this approach, the divs will align horizontally while maintaining the specified structure and spacing.
