in the <table> tag, put a border="0" (like <table border="0">) - this will hide the grid in all browsers, not just in firefox
A web browser (like Internet Explorer, Mozila Firefox, Google Chrome, Safari, etc)
use this: <br> for new lines, and use this: &nbsp; for spaces
A "browser" is a program that can render/read HTML.
As subtle distinction between HTML and browser is that HTML code does not produce the form; the browser produces the form. The browser interprets HTML code to determine how to display page content.
There are numerous websites where you can find free information on HTML, HTML tables and HTML programming. Some examples are Tizag, HTML Code Tutorial, Quackit, HTML Tables, and HTML Goodies. That should be more than enough to get you started.
HTML is not compiled. It is interpreted. Whichever browser you use is the interpreter for HTML. That is the job of a browser: to read and interpret HTML and then display the page.
HTML is read by a browser and a browser works at the Application Layer.
HTML results can be shown in a web browser. They are the one that can display the work of a browser.
HTML tag provides the charset, version number to the browser. It also passes the various attributes to the browser.
Each browser has its own individual version, which does not relate to HTML. The current version of HTML is version 5 and any up to date browser should be able to manage it.
Comments are not displayed by the browser, but they can help document your HTML source code.
HTML markup tags provide formatting instructions to a browser. An HTML document tells the browser how to display the content on a webpage.
