Responsive Design

my notes on bootstrap 3

bootstrap (twitter): http://getbootstrap.com/getting-started/#download
- with built-in UI elements, 12 grid scaffolding
amazium (less)
- 960 grid into 1200 grid
960 grid system → unsemantic (sass)
- 12 or 16 grid system

Responsive Elements

responsive image map:
- image map basic and tool
- (works) js method to recalculate map when image resize (need to call when image visible): https://github.com/davidjbradshaw/image-map-resizer
- (not sure, not on attemp) instead map, it use generated svg method: https://imagemapper.noc.io/#/
  - https://stackoverflow.com/questions/19484707/how-can-i-make-an-svg-scale-with-its-parent-container

- (similar js but old) https://github.com/stowball/jQuery-rwdImageMaps

CSS Pre-processor

SASS/SCSS/LESS likes, it turns what you write into a css code
- in SASS, variable support, nesting

HTML pre-processor

HTML5 Elements (Widgets)

Video

code for video

<style>
video#bgcover{ 
  min-width:100%; min-height:100%; 
  width: auto; height:auto; 
  background: url(./image/my_video.png) no-repeat;
  background-size: cover;
</style>
 
<!-- if no poster, it will loop -->
<video id='bgcover' autoplay poster='./image/my_video.png'>
  <source  src='./image/my_video.ogv' type='video/ogv' />
  <source  src='./image/my_video.webm' type='video/webm' />
  <source  src='./image/my_video.mp4' type='video/mp4' />
</video>

center image in div

horizontal center image, just put div text-align as center
```
.div_name{ text-align: center; } 
```
another way is to put image to respond to div center, margin itself, and it need to be block not inline to have margin
```
.img_name{ margin: auto; display: block;} 
```

3rd method is to use latest div tech, flex, put div as flex

.div_name{
    display: flex;
    justify-content: center;
}

in 3rd method, as it is like hbox default, those elements inside div is like widget in UI, to align those widgets together, set align-items in .div_name

.div_name{
    display: flex;
    justify-content: center;
    align-items: center; /* flex-start: align top, flex-end: align btm; */
}

function toggleColor() {
  var myButtonClasses = document.getElementById("btn1").classList;
 
  if (myButtonClasses.contains("blue")) {
    myButtonClasses.remove("blue");
  } else {
    myButtonClasses.add("blue");

  if (myButtonClasses.contains("red")) {

html select dropdown and remove focus

problem: when select dropdown, the select focus still stuck on the dropdown list, (when you press arrow key)

solution: to remove focus after choose, add onchange event and remove its focus

const choice_input = document.querySelector(".my_choice")
choice_input.onchange = function(event){
choice_input.blur() // remove focus from this input
}
// also if you have onload function, you can add this to onload to reset last choice when refresh browser
const tmp_choice_input= document.querySelector(".my_choice")
tmp_choice_input.selectedIndex = "0";
