Get article from a web site to web viewer

hello needed help to send a link to the web viewer. but just receive the article. ie delete the header and footer of the website

If you would like to display a website in your app but delete the header and footer, you can copy the website article and paste it into your app directly, or create an identical website without the header and footer. Or you could adjust the size of the web viewer so that it is larger than the app page, and the header and footer get cut off.

I need to get several articles, depending on what the user selects. an idea of ​​copying the article and pasting does not work for me. because the articles contain an image gallery or sometimes even a video.
