How Can I Effectively Remove Whitespace Between HTML Elements?

Ignoring Whitespace in HTML: The 'white-space-collapse' Property

Despite the prevalence of HTML and CSS, it's surprising that there isn't a direct way to instruct the browser to ignore whitespace. This can lead to frustrating situations when elements such as images are mistakenly separated by unwanted spaces.

The 'white-space-collapse' Property

While there is no universally supported solution, the CSS property 'white-space-collapse' offers a promising approach. By setting this property to 'discard' on the parent element of the images, you can effectively eliminate any whitespace between them.

#parent_of_imgs { white-space-collapse: discard; }

Drawbacks

Unfortunately, this solution is hindered by a significant drawback: no major browser (as of current knowledge) has implemented the 'white-space-collapse' property. This means that despite its potential effectiveness, it remains impractical for widespread use.

Alternative Solution

As an alternative, you can resort to adding HTML comments in between the images. While not ideal, this technique can prevent the browser from rendering any visible whitespace.

<p>
  <!--
    --> <img src="." alt="" /> <!--
    --> <img src="." alt="" /> <!--
    --> <img src="." alt="" /> <!--
    --> <img src="." alt="" /> <!--
  -->
</p>
