How to Make Blinking/Flashing Text With CSS 3

How to make blinking/flashing text with CSS 3

You are first setting opacity: 1; and then you are ending it on 0, so it starts from 0% and ends on 100%, so instead just set opacity to 0 at 50% and the rest will take care of itself.

Demo

.blink_me {  animation: blinker 1s linear infinite;}
@keyframes blinker {  50% {    opacity: 0;  }}

<div class="blink_me">BLINK ME</div>

How to create Blinking text with CSS only?

Your issue is that you use transition and animation in 1 line.

Change your transition to animation like below. Also changed the opacity to 1 -> 0 -> 1 instead of 1 -> 0.5 -> 0 because you want to have a blink not 1 -> 0 and than no transition to 1 opacity again.

A fiddle: https://jsfiddle.net/kc6936cw/

.blinking {

    animation: opacity 2s ease-in-out infinite;
    opacity: 1;
}

@keyframes opacity {
  0% {
    opacity: 1;
  }

  50% {
    opacity: 0
  }

  100% {
    opacity: 1;
  }
}

Edit: jtmingus comment could also be used:

You could also add the alternate tag to the end instead of going from 1 -> 0 -> 1. That would look like animation: opacity 2s ease-in-out infinite alternate;

How to make flashing text in Css?

Yes!
You can use CSS3 animations to handle that now.

HTML:

 <h1 class="flash">Look at me flash</h1>

CSS:

.flash {
   animation-name: flash;
    animation-duration: 0.2s;
    animation-timing-function: linear;
    animation-iteration-count: infinite;
    animation-direction: alternate;
    animation-play-state: running;
}

@keyframes flash {
    from {color: red;}
    to {color: black;}
}

Here's a link to a codepen to see it in action.

Blink a text inside div twice using css

#text {  font-weight: bold;  font-size: 20px;  animation-name: blink;  animation-duration: 5s;   animation-iteration-count: infinite;}
@keyframes blink {    0% {color: pink}    50% {color: black;}    100% {color: pink;}    }

<div id="text">  No more lights</div>

Imitating a blink tag with CSS3 animations

The original Netscape <blink> had an 80% duty cycle. This comes pretty close, although the real <blink> only affects text:

.blink {  animation: blink-animation 1s steps(5, start) infinite;  -webkit-animation: blink-animation 1s steps(5, start) infinite;}@keyframes blink-animation {  to {    visibility: hidden;  }}@-webkit-keyframes blink-animation {  to {    visibility: hidden;  }}

This is <span class="blink">blinking</span> text.

How do I put a text on top blinking div

Here you go...

You only set border-color: #fff to the @keyframes that's why only the border was blinking. You also have to set opacity: 0 to the @keyframes if you want blinking text too.

.boxed {
  border: 1px solid #007BFE;
  animation: blink 1s linear infinite;
}

@keyframes blink {
  50% {
    opacity: 0;
    border-color: #fff;
  }
}

I would like to build the blinking text effect that changes? in css.

Hope this works for you.

document.addEventListener('DOMContentLoaded',function(event){  // array with texts to type in typewriter  var dataText = [ "Amsterdam.", "Newyork", "Bengaluru", "sydney"];    // type one text in the typwriter  // keeps calling itself until the text is finished  function typeWriter(text, i, fnCallback) {    // chekc if text isn't finished yet    if (i < (text.length)) {      // add next character to h1     document.querySelector("h1").innerHTML = text.substring(0, i+1) +'<span aria-hidden="true"></span>';
      // wait for a while and call this function again for next character      setTimeout(function() {        typeWriter(text, i + 1, fnCallback)      }, 100);    }    // text finished, call callback if there is a callback function    else if (typeof fnCallback == 'function') {      // call callback after timeout      setTimeout(fnCallback, 700);    }  }  // start a typewriter animation for a text in the dataText array   function StartTextAnimation(i) {     if (typeof dataText[i] == 'undefined'){        setTimeout(function() {          StartTextAnimation(0);        }, 20000);     }     // check if dataText[i] exists    if (i < dataText[i].length) {      // text exists! start typewriter animation     typeWriter(dataText[i], 0, function(){       // after callback (and whole text has been animated), start next text       StartTextAnimation(i + 1);     });    }  }  // start the text animation  StartTextAnimation(0);});

body {  background-color: #ef3ef4;  height: 100%;  font-family: 'tradegothiclt-bold', sans-serif;}
h1 {  font-size: 5em;  color: white;  text-transform: uppercase;}
span {  border-right: .05em solid;  animation: caret 1s steps(1) infinite;}
@keyframes caret {  50% {    border-color: transparent;  }}
