CSS3 Animations - HTML5 DevCon 2013


Helped write "HTML5 and Css3 for Real World" book I like
Has writtwn another book on css3 animations, looks like its on github!


animation: spirit and life, "breath life into things"

Animations add visual feedback to users; create more immersive websites, more fun,
 if you have an img then why not animate

Two Animation Routes in css3
1. transitions
    - these are fast
    - but no built in way to repeat, so can't loop e.g. boucing type spring
    - best for on/off type stuff
    - can only do a to b

2. keyframes (aka css anmiations)
    - a little slower cos browsers not doing


Transitions
2 required properties: transition-property and transition-duration
There is a shorthand for that css styel
You can include multiple transitions on 1 line

Site she likes:
 delta.com  their search box top right expands on focus
 shareagift.com as you scroll then notice the top nav bar animation
 webplatform.org example of cool css lightbox

You an create that arrow using a div and css, no need for image.

She showed

jsbin.com like jsfiddle?
dabble.com

"10 secrets you may not know about css"

lightbox: spreads tall then goes wide or wide and then tall



Keyframes aka CSS Animations
Two step process to setup
1. setup frames
2. call animation property

To do 3D animations you must set perspective. 800 seems to be the sweet spot

Animate css is a great site for seeing animations, and you can see code too



Tip: Don't just background image, animate it. e.g. red img on strikebedt.com

Many from the protractor test suite category detailed task syntax example load page load a page browser.get('yoururl') browser btn actions browser back/forward browser.navigate().back() OR browser.navigate().forward() access elements on page See Protractor API list and examples from Protractors test suite access by angular ngmodel name (must match ngmodel in the html) this is the preferred approach element(by.model('person.name')); access by the css id on the page e.g, #user_name (but this can be brittle) element(by.id('user_name')) access angular binding to get generated value i.e. for {{}} element(by.binding('person.concatName')); access angular repeat list data (must match repeat stmt in the html) See Protractor test suit l...

react-select stacking order bug, z-index, layers and stacking

Image
Had to fix a tricky bug related to react-select recently (our Dropdown component wraps react-select). Here's the how the bug manifested. Dropdown does not overlay dynamically added content below it Variations of this have been reported since 2017. But I tried all the suggestions in the comments and none worked for me. I also tried wrapping the Dropdown in a div and changing z-index to be higher as well as making absolute position but no success. Changing the elements order in the html source and then reordering using flexbox order does work but it breaks the tabbing flow and is not recommended from an accessibility standpoint. One issue is the Dropdown is in a container and is constrained by the containers z-index. No matter how I change the Dropdowns z-index, its container is stacked below the next in stacking order. Google Chrome debugger layers tool provides a cool way to visualize layers. Could be better but helps, check it out below. You have to look closely but you can see h...
