Lab 15 Transitions

Goal

Learn

<template> - is a mechanism for holding HTML that is not to be rendered immediately when a page is loaded but may be instantiated subsequently during runtime using JavaScript.

Think of a template as a content fragment that is being stored for subsequent use in the document. While the parser does process the contents of the template element while loading the page, it does so only to ensure that those contents are valid; the element's contents are not rendered, however.

<template id="template">
  <div>Click me</div>
</template>

<dialog> - represents a modal or non-modal dialog box or other interactive component, such as a dismissible alert, inspector, or subwindow. JavaScript should be used to display the <dialog> element.

<dialog>
    <p>Thank you for ordering</p>
</dialog>

<select> - represents a control that provides a menu of options.

<option> - is used to define an item contained in a select.

HTML

<label for="pet-select">Choose a pet:</label> <select name="pets" id="pet-select"> <option value="">--Please choose an option--</option> <option value="dog">Dog</option> <option value="cat">Cat</option> <option value="hamster">Hamster</option> <option value="parrot">Parrot</option> <option value="spider">Spider</option> <option value="goldfish">Goldfish</option> </select>

p:before{
    content:url(images/image1.jpg);
}
p:after{
    content:url(images/image2.jpg);
}

After and before pseudo classes are used to add content with CSS before or after the content of a HTML element. Before and after can only be used with container elements. This means the element must have an opening and closing tag.

Today you will be using before and after with the content property to add icons to different elements. Content can also be used to add text, quotes, a number counter, or a gradient.

See content property uses here

header{
    background-color:red;
    transition-property:background-color;
    transition-duration:5s;
    transition-timing-function:ease-in;
    transition-delay:1s;
}

CSS Transitions provide a way to control animation speed when changing CSS properties. Instead of having property changes take effect immediately, you can cause the changes in a property to take place over a period of time. For example, if you change the color of an element from white to black, usually the change is instantaneous. With CSS transitions enabled, changes occur at time intervals that follow an acceleration curve, all of which can be customized.

What properties can be transitioned?

ALL OF THESE!

Transition Properties

transition-property:background-color;

transition-property

Specifies the name or names of the CSS properties to which transitions should be applied. Only properties listed in the declaration are animated during transitions; changes to all other properties occur instantaneously as usual.

transition-duration:2s;

transition-duration

Specifies the duration over which transitions should occur. You can specify a single duration that applies to all properties during the transition, or multiple values to allow each property to transition over a different period of time.

transition-timing-function:ease-in;

transition-timing-function

Specifies a function to define how intermediate values for properties are computed. Timing functions determine how intermediate values of the transition are calculated. Most timing functions can be specified by providing the graph of the corresponding function, as defined by four points defining a cubic bezier. Here is a web page showing the various timings you can use.

transition-delay:1s;

transition-delay

Defines the wait between the time a property is changed and the transition actually begins.

transition: <property> <duration> <timing-function> <delay>;

transition

The shorthand CSS declaration for all of the properties above. Below is the order of the values.

So for example, the following two declarations accomplish the exact same thing.

header{
    background-color:red;
    transition-property:background-color;
    transition-duration:5s;
    transition-timing-function:ease-in;
    transition-delay:1s;
}
header{
    background-color:red;
    transition:background-color 5s ease-in 1s;
}

Practice

Experiment Try adding a transition on the <a> for the background color with a 1 second duration with a timing function of ease-in-out. Once you have added the transition hover over the a. Notice how the color takes time changing from light to dark and back again.
Now add a font color of blue to the paragraph when you hover. Then add a transition to the paragraph that will delay the font color for .5 seconds and take .7 seconds to change.

Open GitHub Desktop (you may need to download the program again if the computers get wiped.)

Couple of things to check in GitHub Desktop.

With your cs-318 repository selected, Click open in Visual Studio code.

Create a new folder called lab15

Create a new files called index.html, about.html, menu.html, and order.html in the lab15 folder

Setup your HTML files

Create your stylesheet

Link your stylesheet to the HTML files

Change Document in the <title> elements to "Brunch"

Add a <header>, <main> and <footer> on every document.

All HTML documents will have the same header

<header>

All HTML documents will have the same footer

<footer>

Index.html.

In the section:

<h2> - About Brunch

<p> - Our Mission - is to satisfy our neighbor's need for coffee and community by providing high quality, direct trade coffee that we all can feel good about.

<img>

<p> - Our Beans - are the result of direct trade. With a handshake, the farmer's crop is purchased for more than they could get on the open market. Through the Friend2Farmer initiative, better coffee is being created, along with a better quality of life for the farmers, their families and their community. Due to the strong relationships being built, we are able to play a part in helping fund local schools and other life-enriching projects within these communities. We believe that nothing's better than waking up and knowing the delicious coffee you're drinking is helping to brew better lives, better coffee and better communities all over the world.

<img>

<p> - Distinctive and Bold - is to inspire a culture of generosity and authenticity; helping to create the kind of community (local + worldwide) that we all want to call home. Locally, by partnering and building strong relationships with local non-profits and businesses to meet the needs of our neighbors. Worldwide, by ensuring that the farmers who provide us our coffee beans, and the communities in which they are apart, are treated equitably.

Back to index page

Create new file called scripts.js and paste in code below.

// gallery component
document.addEventListener('DOMContentLoaded', function(){
	var rotate = function(component, step){
		// figure out width of container
		var slide = component.querySelector('.slide');
		let slideWidthVw = ((slide.offsetWidth / document.documentElement.clientWidth)-1) * 100;
		var left = Number(slide.style.left.replace('vw', ''));
		left += step * 100;
		if(left > 0) left = 0;
		if(left < -slideWidthVw) left = -slideWidthVw;
		slide.style.left = left+'vw';
	};

	var components = document.querySelectorAll('.gallery');
	for(var i = 0; i < components.length; i++){
		var component = components[i];
		component.querySelector('.left').addEventListener('click', function(){
			rotate(component, 1);
		});
		component.querySelector('.right').addEventListener('click', function(){
			rotate(component, -1);
		});
	}
});

Final Steps

Validate your HTML.

Lint your CSS at jigsaw.w3.org. This is a new up to date validator.

Now look at GitHub Desktop. You should see all of your files listed out in the left column.

GitHub Desktop files listed

Now you are going to commit your changes.

With all of the files checked. Fill out the Summary field in the bottom left and then click Commit to main.
Committing is staging the files, so they can be pushed to the repository hosted at GitHub.

GitHub Desktop Summary field.

Now you want to push your changes to the Repository. Now if you access the repository from another computer Lab15 will be there. After you push in the top right of the nav it should say "Fetch Origin" instead of "Push Origin"

GitHub Push Origin
