Achieve a perfectly centered and responsive image placement on a webpage accompanied by a countdown timer

I've been trying to design an HTML page with a countdown feature, and I want to place an image above it that is centered and responsive. Despite my efforts, I haven't been able to achieve the desired responsiveness. I envision it looking like this:

However, when I resize the page, it ends up looking like this (an utter disaster):

https://i.sstatic.net/aBPSi.png

I attempted setting the "width: 100%", but then the image becomes huge, forcing me to use "width:20%". How can I make this image responsive like the countdown?

Below is the code snippet:

var target_date = new Date("January 20, 2020");
var days, hours, minutes, seconds; // variables for time units
var countdown = document.getElementById("tiles"); // get tag element
getCountdown();
setInterval(function() {
  getCountdown();
}, 1000);

function getCountdown() {
  // find the amount of "seconds" between now and target
  var current_date = new Date().getTime();
  var seconds_left = (target_date - current_date) / 1000;
  days = pad(parseInt(seconds_left / 86400));
  seconds_left = seconds_left % 86400;
  hours = pad(parseInt(seconds_left / 3600));
  seconds_left = seconds_left % 3600;
  minutes = pad(parseInt(seconds_left / 60));
  seconds = pad(parseInt(seconds_left % 60));
  // format countdown string + set tag value
  countdown.innerHTML = "<span>" + days + "</span><span>" + hours + "</span><span>" + minutes + "</span><span>" + seconds + "</span>";
}

function pad(n) {
  return (n < 10 ? '0' : '') + n;
}
body {
  font: normal 13px/20px Arial, Helvetica, sans-serif;
  word-wrap: break-word;

}

  left: 600px;
  top: 0px;
  width: 20%;

}

Answer №1

Many of your HTML elements are using position: absolute, which is causing the issue. To center them, consider using a different approach like flexbox:

var target_date = new Date("January 20, 2020");
var days, hours, minutes, seconds; // variables for time units

var countdown = document.getElementById("tiles"); 

getCountdown();

setInterval(function () { getCountdown(); }, 1000);

function getCountdown(){

    var current_date = new Date().getTime();
    var seconds_left = (target_date - current_date) / 1000;

    days = pad( parseInt(seconds_left / 86400) );
    seconds_left = seconds_left % 86400;

    hours = pad( parseInt(seconds_left / 3600) );
    seconds_left = seconds_left % 3600;

    minutes = pad( parseInt(seconds_left / 60) );
    seconds = pad( parseInt( seconds_left % 60 ) );

    countdown.innerHTML = "<span>" + days + "</span><span>" + hours + "</span><span>" + minutes + "</span><span>" + seconds + "</span>"; 
}

function pad(n) {
    return (n < 10 ? '0' : '') + n;
}
body{ 
    font: normal 13px/20px Arial, Helvetica, sans-serif; word-wrap:break-word;

Your logo and countdown should be within the same parent section element with display: flex applied.
