When responding to a credentialed request: If a request includes a credential (most commonly a Cookie header) and the response includes an Access-Control-Allow-Origin: * header (that is, with the wildcard), the browser will block access to the response, and report a CORS error in the devtools console. Cookie in the request (line 10) may also be suppressed in normal third-party cookie policies. Some businesses demand a detailed list of requirements backed by a well-thought-out technical specification, while others are content with a shallow approach. Note that simple GET requests are not preflighted, and so if a request is made for a resource with credentials, if this header is not returned with the resource, the response is ignored by the browser and not returned to web content. CORS also relies on a mechanism by which browsers make a "preflight" request to the server hosting the cross-origin resource, in order to check that the Since the request uses a Content-Type of text/xml, and since a custom header is set, this request is preflighted. Since screen dimensions and width in CSS pixels vary widely between devices (for example, between phones and tablets, and even between different phones), content should not rely on a particular viewport width to render well. Modern CSS layout techniques such as Flexbox, Grid Layout, and Multicol make the creation of these flexible grids much easier.
