There are some familiar โitemsโ with todayโs additional functionality to yesterdayโs CSS3 Button Animation Transition Game Tutorial โฆ and some other matters we encourage you to consider, the primary one of these being โฆ
- the benefits of multiple class HTML element definitions where the Cascading in CSS comes into (its hierarchical) play with first class being a โtemplateโ one refined by second class โlocalizingโ styles โฆ we instigated before familiar โฆ
- localization of our Animated Button Game allowing the user to define their own โPhrase or Proverbโ versus โExplanation of phrase or proverbโ relationship โฆ and our favourite โฆ
- sharing email (via client email a link to mailto: href element) mechanism for โฆ
- email link to game โฆ and/or โฆ
- email link to game with any localizations and as a challenge to an emailee (with the same order of questioning) and a โ versus otherscore/othergoesโ flagging of score HTML element
- interfacing to the user via new โcharacterโ and emoji and โemoji plus sup buttonโ (as a new means by which we can effect a multiple emoji โfeelโ)
The (new version of the) gameโs HTML and CSS and Javascript animated_button_gamehtm changed thisway for this work today, the biggest block of change representing how that CSS started using multiple class definitions like โฆ
class="button button1"
โฆ and reduced the CSS definition from right hand side to left hand side as below โฆ
New multiple class CSS | Old single class use CSS |
---|---|
<style> select { width:70%; border: 2px solid pink; } .button { .button span { .button span:after { .button:hover span { .button:hover span:after { .button1 { .button1 span:after { .button2 { .button2 span:after { .button3 { .button3 span:after { .button4 { .button4 span:after { .button5 { .button5 span:after { .button6 { .button6 span:after { .button7 { .button7 span:after { .button8 { .button8 span:after { |
<style> select { width:70%; border: 2px solid pink; } .button1 { .button1 span { .button1 span:after { .button1:hover span { .button1:hover span:after { .button2 { .button2 span { .button2 span:after { .button2:hover span { .button2:hover span:after { .button3 { .button3 span { .button3 span:after { .button3:hover span { .button3:hover span:after { .button4 { .button4 span { .button4 span:after { .button4:hover span { .button4:hover span:after { .button5 { .button5 span { .button5 span:after { .button5:hover span { .button5:hover span:after { .button6 { .button6 span { .button6 span:after { .button6:hover span { .button6:hover span:after { .button7 { .button7 span { .button7 span:after { .button7:hover span { .button7:hover span:after { .button8 { .button8 span { .button8 span:after { .button8:hover span { .button8:hover span:after { |
Cute, huh?!
Previous relevant CSS3 Button Animation Transition Game Tutorial is shown below.
The recent CSS3 Transition Game Tutorial had us examining CSS3 (Cascading Style Sheet) specification โTransitionsโ as tools for animation styling. Today we โฆ
- apply such โtransitionโ thinking to the animation of HTML button elements (as inspired by https://www.w3schools.com/css/tryit.asp?filename=trycss_buttons_animate1 thanks) โฆ in terms of โฆ
- creating a game whereby the user links a (most often based on Wikipedia sources, thanks) โproverb or phrase explanationโ the game randomly selects for the user in an HTML select element dropdown (made to be โreadonlyโ via the use of the disabled=โdisabledโ attribute) โฆ to โฆ
- HTML button elements initially showing a prefix โฆ that when โฆ
- hovered over CSS3 โtransitionโ animation also channelling the checked against the :after selector to show a full proverb or phrase as the user selection โฆ
- Javascript checked against data attributed (to hide from โnosyโ users) the link to โexplanationโ correct matches to โฆ
- increase the userโs score in the gameโs HTML and CSS and Javascript animated_button_game

Do you remember a recent โStop Pressโ explaining a neat way to get mobile platforms to effectively map their onclick event logic to an onmouseover event based Javascript logic set, via the application of โฆ
onclick=""
โฆ HTML element (today that being a button element) logic? Well, today that is used again to allow for this game to be played on mobile devices, but just with those users clicking buttons rather than the โhoverโ that a non-mobile user does to play the same game.

Yesterdayโs CSS3 Transition Primer Tutorial started us thinking about CSS3 (Cascading Style Sheet) specification โTransitionsโ, and there, we intimated that they could be used to serve up to the web application user simple animation functionality. Today, we go a bit further down that road exporing a few more ideas in this line of work, along the way using โtransitionsโ in a simple spider game as below โฆ
Added into the โtransitionsโ usage, building on yesterday, are the concepts (all available to read further on here, thanks) โฆ
- multiple โconceptโ transitions
- transition-timing-function modes of use
- transition (CSS styling) definition separated out into its 3 constituent parts โฆ
- transition-property
- transition-delay
- transition-duration
โฆ as per โฆ
<style>
.cdiv {
width: 300px;
height: 200px;
background: red;
-webkit-transition-delay: 3s;
transition-delay: 3s;
-webkit-transition-property: height, width; /* Safari */
transition-property: height, width;
-webkit-transition-duration: 4s, 22s; /* Safari */
transition-duration: 4s, 22s;
}
.cdiv:hover {
width: 600px;
height: 400px;
}
</style>
The game today recalls the recent CSS3 Background Size Contain and Cover Primer Tutorial use of the CSS background-size contain and cover attribute values that we harness to (lamely, admittedly) make (just one of our) spiders rear up, and mildly scare our web application game users (perhaps a few of which are rolling on the floor in apopleptic laughter).
The HTML and CSS and Javascript liverunโs css3_transitions
htm HTML and CSS and Javascript source code, changed thisway.
Previous relevant CSS3 Transition Primer Tutorial is shown below.
The CSS3 (Cascading Style Sheet) specification introduced โTransitionsโ to CSS styling of web pages. A CSS3 โtransitionโ โฆ
CSS3 transitions allows you to change property values smoothly (from one value to another), over a given duration.
Today, we use the CSS :hover selector as the basis for transitions in our liverunโs css3_transitions
html HTML and CSS source code.
As you might surmise using this web application, CSS3 โTransitionsโ can act like simple animations.
Stop Press
The CSS :hover selector is not a โgood fitโ (euphemism for โit doesnโt work, Bud!โ) on mobile platforms. Looking around the โnetโ got to this great link, thanks, which suggested adding onlick=โโ on all relevant :hover selector HTML elements, to allow for (and it only really makes sense when the real onclick event meaning is not needed) the onclick event to be simulating the onmouseover event, for those mobile platforms missing the real onmouseover event.
