For example in the webpage shown above, there were 6 segments of <div class="ModalWrap">......</div>
and I removed 5 manually.
is there a Chrome plugin that can do this automatically (remove all 6 ) when loading the webpage from the Internet?
Stylish may fill your need; you can write CSS to alter the presentation of specific pages, sites, or universally. For your particular case, you'd target the site or page, and add CSS for
div.ModalWrap { display: none; }
