How Can I Connect HTML Divs with Lines Using Only HTML and CSS?

Connecting HTML Divs with Lines without Canvas

Connecting multiple HTML divs with lines can enhance the visual representation and layout of a webpage. While using a canvas element is a common approach, it's also possible to achieve this in HTML and CSS alone.

One method is to utilize SVG (Scalable Vector Graphics) lines. SVGs allow for the creation of vector-based graphics that are rendered using XML code.

HTML Code:

To begin, define the divs you want to connect:

<div>
<p><strong>SVG Line Code:</strong></p>
<p>Create an SVG line element, specifying the coordinates that connect the divs:</p>
<pre class="brush:php;toolbar:false"><svg width="svg width" height="svg height">
  <line x1="x-coordinate of div1 center" y1="y-coordinate of div1 center" x2="x-coordinate of div2 center" y2="y-coordinate of div2 center" stroke="line color"></line>
</svg>

For example, if you want to connect the centers of the divs defined above, you would use the following code:

<svg width="500" height="500">
  <line x1="50" y1="50" x2="350" y2="350" stroke="black"></line>
</svg>

CSS (optional):

You can use CSS to style the line, such as setting its thickness or color:

svg line {
  stroke-width: 2px;
}

Advantages of Using SVG Lines:

• Lightweight and efficient
• Only requires HTML and CSS
• Allows for precise control over line positioning
