#Html resize image update
The browser will render the page, wait for the image source to load, and then update the height of the image element. If we want it to show a bit smaller we can set the width to 240, the browser will then automatically calculate the height to be 180. Imagine we have a cat picture with an aspect ratio of 4:3, in other words, it’s dimensions are 4032 × 3024, that’s a lot of cat. Our first choice is to set only one size property, either width or height, the browser will automatically calculate the size of the other edge. Let’s look at the different options we have to size images while keeping their aspect ratio in check. We can resize images proportionally with HTML image tags or CSS background styles. This.Sometimes images are just too big to display on the web page. $('.picture-frame img:visible').each(function $this.css('height', parent.height() + 'px') $this.css('width', parent.width() + 'px')
If ($this.width() = parent.width() || $this.height() = parent.height()) Var parent = $this.closest('.picture-frame') Margin-top: -4px /* Inline images have a slight offset for some reason when positioned using vertical-align */īorder: 0 /* Remove border on images enclosed in anchors in Internet Explorer */Įdit: Possible further improvement using JavaScript (upscaling images): function fixImage(img) It'll only work if the container has a specified size ( max-width and max-height don't seem to get along with containers that don't have concrete size), but I wrote the CSS content in a way that allows it to be reused (add picture-frame class and px125 size class to your existing container). I've replaced it with inline based positioning which not only works fine in both Internet Explorer 7 and Internet Explorer 11, but it also requires less code. You can also set image to be aligned as you want (for example, for a product picture on an infinite white background you can position it to center bottom easily).Įdit: Previous table-based image positioning had issues in Internet Explorer 11 ( max-height doesn't work in display:table elements). You can set max-width and max height independently the image will respect the smallest one (depending on the values and aspect ratio of the image). * This is the key part - position and fit the image to the container */ * This is for responsive container with specified aspect ratio */ Most vector drawing programs out there will set these properties when exporting an SVG file, so you will have to manually edit your file every time you export, or write a script to do it.īox-shadow: 3px 3px 6px rgba(0, 0, 0. You just have to ensure that the SVG file has none of these properties set in the tag: height If your image is an SVG, which is a variable-sized vector image format, you can have the expansion to fit the container happen automatically.
If your image and container are both "portrait shaped" or both "landscape shaped" (taller than they are wide, or wider than they are tall, respectively), then it doesn't matter which of height or width are "%100".If you set both to "100%", your image will be stretched.Ĭhoosing whether to do height or width depends on your image and container dimensions: To resize an image proportionally, you have to set either the height or width to "100%", but not both. Currently there is no way to do this correctly in a deterministic way, with fixed-size images such as JPEGs or PNG files.
