Tag Image Resolution For Free

Use the Auto Value for Width and the max-height Property to Resize the Image in CSS. We can use the auto value for width and set it's max-height to 100% so as to fit within the container it is placed in. In this way, we can prevent overriding any default width, and thus prevent distortions within the image.

The <img> tag is used to embed an image in an HTML page. Images are not technically inserted into a web page; images are linked to web pages. The <img> tag creates a holding space for the referenced image.

The <resolution> CSS data type, used for describing resolutions in media queries, denotes the pixel density of an output device, i.e., its resolution. On screens, the units are related to CSS inches, centimeters, or pixels, not physical values.

We can resize the image by specifying the width and height of an image. A common solution is to use the max-width: 100%; and height: auto; so that large images do not exceed the width of their container. The max-width and max-height properties of CSS works better, but they are not supported in many browsers.

The image resolution is defined as the number of image pixels per unit length, e.g., pixels per inch. By default, CSS assumes a resolution of one image pixel per CSS px unit; however, the image-resolution property allows a different resolution to be specified.

The resolution feature is specified as a <resolution> value representing the pixel density of the output device. It is a range feature, meaning that you can also use the prefixed min-resolution and max-resolution variants to query minimum and maximum values, respectively.

The image-resolution CSS property specifies the intrinsic resolution of all raster images used in or on the element. It affects content images such as replaced elements and generated content, and decorative images such as background-image images.

Image dimensions are 'properties' which can be expressed in either the HTML <img> element, as width="150" height="100" attributes in the tag; or, the CSS as style rules applying to specific images. If we wish to scale the image, then we use width OR height, and let the other fall in.
