Responsive web design keeps growing, but one aspect that keeps challenging designers is the use of images. Designers have to use various methods to come up with flexible images for responsive design. The use of adaptive images with PHP script is one option that you can consider for your site. Adaptive images resize automatically after detecting the screen size of your website visitor. These types of images are default with PHP and don’t need any markup changes.
Use of Online Platforms
Some online platforms make it possible for web designers to resize responsive images. Publishing platforms like WordPress come with plugins that allow resizing of images. These plugins use different methods to make images responsive such as cropping, splitting, and resizing the width and length and resizing the percentage, among others.
HTML 5 Picture Element
The use of <picture> element on HMTL 5 facilitates the setup of images on different sources. By using the source tag, you can specify the conditions that an image should load under. For instance, an image can load when visitors use specific media queries or pixel density. The HTML 5 picture elements make it possible to load images of appropriate file sizes, which maximises bandwidth usage. It also allows loading of high-resolution images.
Focal point allows responsive images by facilitating cropping and focus control. Use of Focal Point for responsive web design is suitable on CSS. The technique allows a designer to specify which part of an image to crop (the focal point). It prevents cropping out important elements of a picture that may impact its appearance and significance. On a large screen, a focal point image will appear normal and then reduce in width as the viewport reduces.
