Images add life to your webpages and draw the attention of viewers. Captions provide extra information about your web images, but they can be difficult to add to webpages without advanced HTML and CSS skills. Here's a reliable method for adding a simple, yet attractive, caption to an image that stays with the image wherever you move it on the webpage.

9 Steps to an HTML Image Caption

Add a caption to an image and move them together wherever you want:

  1. Add an image to your webpage.
  2. In the HTML for your webpage, place a div tag around the image:
    <div><img src="URL" alt="alternate text" width="width" height="height" /></div>
  3. Add a style attribute to the div tag:
    <div style=""><img src="URL" alt="alternate text" width="width" height="height" /></div>
  4. Set the width of the div to the same width as the image, with the width style property:
    <div style="width:image width px;"><img src="URL" alt="alternate text" width="width" height="height" /></div>
  5. For captions that are slightly smaller than the surrounding text, add a font-size property to the div style:
    <div style="width:image width px; font-size:80%;"><img src="URL" alt="alternate text" width="width" height="height" /></div>
  6. Captions look best if they are centered below the image, so add a text-align property to the style attribute:
    <div style="width:image width px; font-size:80%; text-align:center;"><img src="URL" alt="alternate text" width="width" height="height" /></div>
  1. Finally, add a little extra space between the image and the caption, by adding a style attribute to the image with a padding-bottom style property:
    <div style="width:image width px; font-size:80%; text-align:center;"><img src="URL" alt="alternate text" width="width" height="height" style="padding-bottom:0.5em;" /></div>
  1. Then add the text caption directly below the image:
    <div style="width:image width px; font-size:80%; text-align:center;"><img src="URL" alt="alternate text" width="width" height="height" style="padding-bottom:0.5em;" />This is my caption</div>

Upload the webpage to your server and test it in a browser.

Captioning Tips

  • Widths: CSS dimensions can be in many different measurements, so you usually must include the measurement type. For example:
    width: 100px;
    However, HTML image dimensions are always in pixels, so you leave the measurement off.
    width="100"
  • If you make the width of the div wider than the image width, the caption may appear beside the image. If this is what you want, then add a <br > tag directly before the caption and after the image tag.
