Ajax in the process of loading the page will appear blank, from the user experience point of view this is very unfriendly, at least let the user know that your website is trying to load, even if it is pretending to load asynchronously, hehe. Often in order to compensate for this shortcoming of ajax, we will add a sentence to the Ajax load: "Data is loading..." In order to better user experience, a small loading icon will be used to let users know that data is loading while waiting, and they will not even feel bored.
Here we provide some loading icon online production and collection, loading icon online production can choose graphics, foreground, background, transparent background, loading speed, so that it is perfectly integrated with your page.
