The clear
attribute: a deprecated method for controlling element flow. This HTML attribute, now considered outdated, was used to prevent content from wrapping around floated elements (like images or tables). Instead of using clear
, modern web development relies on CSS for layout control.
The clear
attribute's functionality is replicated using the CSS clear
property. Here's a comparison:

<br clear="left"></br>
Modern CSS:
<br style="clear: left;"></br>
(Note: inline CSS, as shown above, is generally discouraged. It's best practice to define styles in a separate CSS file or within <style></style>

Example: Preventing text from wrapping around a right-aligned image.
<p><img src="/static/imghwm/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/174061669131942.jpg?x-oss-process=image/resize,p_40" class="lazy" alt="clear (HTML attribute) " /> The rest of the day was a lazy one, partly spent by the complex pool, partly inside watching British TV, but we couldn't be doing this for the rest of the holiday. Already we were missing having the car! <br style="clear: both;"></br> I decided to check out what the weather would be doing for the next few days, as that would help us make any decisions about future excursions. </p>
