Reversing the effect of declaring height: auto in CSS

I am currently integrating new code into an existing WordPress theme. The section where the new code is placed is being affected by this line in the style sheet:

#content img {
    height: auto; }

My code, which runs within a plugin/widget, interacts with thumbnail images and displays them within an img tag. Depending on the image size, I include either a height or width attribute in the tag (the width attribute functions correctly). However, the height attribute is being disregarded due to the height: auto declaration.

The smaller box within #content is identified as #CPGimage. I can override the height setting, but I need to determine the appropriate height value based on the image dimensions. For example, if the maximum desired width is 100 and the maximum desired height is 100, and the image size is 100x200, I would set the height attribute of the img tag to 100.

Is there a way to negate the height declaration under #content or somehow instruct it to obtain the height from the img tag?

Answer №1

When aiming to restrict the maximum height of an image, have you considered utilizing the CSS property max-height?

Answer №2

For a more modern approach, avoid using width or height attributes and utilize CSS:

document.getElementById('myImg').style.height = '32px';

If you are using jQuery, the following code can also achieve the same result:

$('#myImg').css({ width: 32 });

Answer №3

Did you give this a shot?

height:inherit

Hope that helps!

Answer №4

Is there a way to set something that tells the content to adjust its height based on the img tag?

If you are using jQuery, you can get the height of the img element like this

var h = $('#content img').height();

Answer №5

Appreciate the advice. Ultimately, I opted to utilize inline css on the img tag like so:

img style="width: 100px;" ....

Prior to this, I was using something along the lines of: img height="100" ....

The issue at hand stemmed from creating the img tag in a php script, where the width or height parameters were not known in advance due to varying size requirements among multiple img tags.

Inline css takes precedence over the html method for setting img height.
