CSS Style Display and Visibility Tic Tac Toe Tutorial

The recent CSS Style Display and Visibility Tutorial had CSS properties …

  • display
  • visibility

… both working to end up with a result, but in practice, as we intimated there, you are likely to just use one or the other. In order for you to see this in action we made another version of the Tic Tac Toe game web application we wrote for HTML Colour Coded Tic Tac Toe Drag and Drop Tutorial featuring [HTMLElement].style.visibility Javascript DOM and CSS definitions rather than its original [HTMLElement].style.display Javascript DOM and CSS definitions, and want to show you them below so you can compare. As you will glean playing Tic Tac Toe in either mode is quite similar, but the “X”s and “O”s to the right present themselves that little bit differently, sometimes, as the game progresses, depending on which style of property you are using. As we intimated yesterday, the use of visibility property allows HTML elements to not be shown but the space for them preserved, unlike with the display property mode of use.

In new windows you can try CSS visibility mode live run involving colourcodedtictactoechalkboard.htm HTML and Javascript and CSS, and which changed in this way to achieve that, or you can try the CSS display mode live run way. It beats getting into the pickle where this is our only way out?!

In yesterday’s Emoji Name Search Geo Chart WorldBank Tutorial we mentioned the CSS topic of “invisibility” as a topic of interest in our “reveal” thought patterns.

Two of the best known ways in CSS to control invisibility (and, hence, visibility) are …

Invisible (style=) Visible (style=) Block Element Visible (style=) Inline Element (eg. span, a, img)
display:none; display:block; display:inline;
visibility:hidden; visibility:visible; visibility:visible;

The W3Schools display and visibility CSS topic webpage is succinct in telling you the difference, as below …

Hiding an element can be done by setting the display property to none. The element will be hidden, and the page will be displayed as if the element is not there:

Example
h1.hidden {
display: none;
}

visibility:hidden; also hides an element.

However, the element will still take up the same space as before. The element will be hidden, but still affect the layout

Which got us to go back to a previous tutorial called CSS Style Display Primer Tutorial where we wrote some HTML and CSS and Javascript to show the display CSS property “in action”, that we “flesh out” today, adding in the layer of CSS property visibility into the mix as well.

In terms of “reveal” thoughts though, it may be more the go for you (with a project you are working on) to just use one or the other CSS property depending on whether you want to …

  • “reveal” a surprise … and have the HTML burst onto the scene via the display property … or …
  • “reveal” by easing the user into thinking there may appear something “in a set aside slot” should I choose a certain course of actions, via the use of the visibility property

Again, you can download source code and rename to styleequalsdisplay.htm and/or try it out at this live run link and/or see what changed to involve the visibility property in this “reveal” topic tutorial.

Cascading Style Sheets (CSS) is a style sheet language used for describing the presentation semantics (the look and formatting) of a document written in a markup language. Its most common application is to style web pages written in HTML and XHTML, but the language can also be applied to any kind of XML document, including plain XML, SVG and XUL.

Cascading Style Sheet methodology is a good technique in order to separate document content from document presentation. For the same content, two different CSS approaches can produce vastly different browser outputs.

With today’s tutorial we concentrate on CSS within HTML and specifically the HTML object’s style.display property, which has a huge number of choices, (and is heavily used by many web designers when building up web pages, I find, being a very close friend with Javascript and the DOM) and have a live run link for you to use with which to experiment. The parent HTML element of our images of Nala the dog is a div element whose own style.display property is shown to you in the document window’s title.

You can download source code and rename to styleequalsdisplay.html
