Are any text or links there solely for search engines rather than visitors? When evaluating your site to see if it includes hidden text or links, look for anything that's not easily viewable by visitors of your site. Hiding a link by only linking one small character-for example, a hyphen in the middle of a paragraph.Text (such as excessive keywords) can be hidden in several ways, including: This means you don't have to pre-create the images, with dynamic resizing taking place on the fly as needed.įor example, you can ensure that each user receives images at the size and device pixel ratio (dpr) that fit their device using the auto value for the dpr and width attributes.Hiding text or links in your content to manipulate Google's search rankings can be seen as deceptive and is a violation of Google's Webmaster Guidelines. You can simply build image URLs with any image width or height based on the specific device resolution and window size. Instead, you should always deliver the right size image for each device and screen size.Ĭloudinary can help reduce the complexity with dynamic image transformations. Ensuring that optimal experience means you should avoid sending high resolution images that get resized client side, with significant bandwidth waste for users of small displays. Responsive web design is a method of designing websites to provide an optimal viewing experience to users, irrespective of the device, window size, orientation, or resolution used to view it.
It uses face detection gravity to ensure that all the faces in the image are retained and centered when the image is cropped:įor an in-depth review of the many ways you can optimize your images, see Image optimization. The following example uses the fill cropping method to generate and deliver an image that completely fills the requested 250x250 size while retaining the original aspect ratio. There are a variety of different ways to resize and/or crop your images, and to control the area of the image that is preserved during a crop.

Keep in mind that this section is only intended to introduce you to the basics of using image transformations with Vue.js.įor comprehensive explanations of how to implement a wide variety of transformations, see Image transformations.įor a full list of all supported image transformations and their usage, see the Transformation URL API Reference. This section provides an overview and examples of the following commonly used image transformation features, along with links to more detailed documentation on these features: Applying common image transformations using Vue.js The video demonstrates the features in Angular, but the concepts are identical for Vue. You can also add the type attribute to the component to define the type of placeholder to use as follows: Placeholder typeĪ low quality, blurred version of the target image.Ī low quality, pixelated version of the target image.Ī low quality, vectorized version of the target image.Ī solid, single color image - the predominant color in the target image. To add a placeholder for a particular image, add the component within the component.

Once the target image download has been completed the placeholder is replaced with the final image. Image placeholdersĪn image placeholder is a lightweight version of a target image that can be downloaded quickly, and will occupy the same location as the intended target image, while the target image is still downloading. To avoid your page content 'jumping' as the elements dynamically adjust to add downloaded images, make sure to add the height and width attributes to the cld-image component, as in the example above. To enable the lazy loading feature for a particular image, add the loading attribute to the component with a value of "lazy". This feature can potentially save bandwidth for images that are not actually viewed, and decrease the time needed to load a page.
Lazy loading tells the browser not to download images that are not yet visible to the user on his screen, and wait until the user scrolls to that image.
