    div>p {background-color: yellow;} Will set paragraphs that's a direct child element of parent element div with background yellow https://www.w3schools.com/cssref/tryit.asp?filename=trycss_sel_element_gt it won't change paragraphs nested within other child elements of the div parent. div p {background-color: yellow;} will change ALL child paragraphs within parent div whether they are nested or not. :root will target the <html> element, it being the outermost containing element (root) * universal selector: meaning target ALL elements. : single colon used for pseudo classes such as :hover, :link, : visited :: used for pseudo element ::after, ::before used to create content before or after a elements content, NOTE: older IE browsers use the single colon, but both can be used for modern better browsers than IE and Edge.

    (1) All form element in your current setup should appear in between <form> and </form> (2) IF using $_POST! The idea is to set a value for each checkbox so when it is submitted it is sent as $_POST array with these values. (4) IF using $_GET! THIS " window.location.assign("deleteVideo.php?id=" + id); " is a $_GET querystring, so ALL $_POST['...'] in 'deleteVideo.php' should be $_GET['...'] instead (3) As these can be multiple values the value of name attribute, should reflect it will be an array of values as in "name='checkbox[]'" (4) The 'id' argument equals WHAT? in onclick="myFunction(id)", its just text or undefined variable? (5) How can $id exist or be defined if it has not retrieved yet! $sql = mysqli_query($database, "SELECT * FROM video WHERE id='$id'"); (6) You need to make your mind up which to use $_GET or $_POST, if using the $_GET by using JavaScript to open this page then empty($_POST['delete'] will never exist. IF sent through GET querystring you would have to use $_GET['..']; instead (6) This if($val=='checked') will never be true, the $id will equal index value of array holding the value which current does not exist? as there is no value assigned to that checkbox.

    It is a nice way to interact with GitHub, but it isnt a GUI for just using Git. Still, very useful since sometimes its hard to remember the commands for pushing to GitHub like "git push origin master"
