you have use webbrowser.invokescript:
// initial text size int textsize = 100; // percentage private void a+_click(object sender, eventargs e) { textsize *= 2; // can modify not increase each time string szfn = "{styletext = \"body { -ms-text-size-adjust:" + textsize + "% }\";styletextnode = document.createtextnode(styletext);stylenode = document.createelement(\"style\");stylenode.appendchild(styletextnode);document.getelementsbytagname(\"head\")[0].appendchild(stylenode);};"; webbrowser.invokescript("eval", szfn); } private void a-_click(object sender, eventargs e) { textsize /= 2; // can modify not decrease each time string szfn = "{styletext = \"body { -ms-text-size-adjust:" + textsize + "% }\";styletextnode = document.createtextnode(styletext);stylenode = document.createelement(\"style\");stylenode.appendchild(styletextnode);document.getelementsbytagname(\"head\")[0].appendchild(stylenode);};"; webbrowser.invokescript("eval", szfn); } check out this post on msdn.
