I’m a newbie in CSS and a new user of stack overflow. I want to design a message-box (speech-bubble), as in the [Design I was given] (https://i.stack.imgur.com/moRgV.jpg):

So I copied a code from the internet that draw something similar, here is the resulting output of my code:

This is my code:

* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}

body {
  min-height: 100vh;
  position: relative;
  background-image: url('images/bg-mobile.png');
  background-repeat: no-repeat;
  background-size: cover;
  font-family: 'Raleway', sans-serif;
}

.container {
  position: absolute;
  top: 40%;
  left: 40%;
  transform: translate(-40%, -40%);
  display: flex;
  flex-direction: column;
  align-items: center;
  justify-content: center;
}

.fylo {
  display: flex;
  flex-direction: column;
  gap: 1.7em;
  width: 320px;
  background: hsl(228, 56%, 26%);
  padding: 2em 3.6em 2.6em 2em;
  margin: 0.5em;
  border-radius: 0.7em;
  border-top-right-radius: 7em;
}

.fylo .second-layer {
  display: flex;
  flex-direction: row;
  gap: 0.9em;
}

.second-layer div {
  width: 30px;
  height: 30px;
  padding: 1.36em;
  background-color: hsl(229, 57%, 11%);
  display: flex;
  align-items: center;
  justify-content: center;
  border-radius: 6px;
}

.flex-container {
  width: 320px;
  background: hsl(228, 56%, 26%);
  padding: 2em 1.5em 3em;
  border-radius: 0.7em;
  display: flex;
  flex-direction: column;
  color: hsl(0, 0%, 100%, .7)
}

.flex-container p {
  margin-bottom: 0.1em;
  text-align: center
}

.inner-flex {
  display: flex;
  margin-top: 0.65em;
  font-size: 0.77rem;
  font-weight: 600;
}

.inner-flex span:nth-child(2) {
  margin-left: auto;
}

progress {
  -webkit-appearance: none;
  -moz-appeareance: none;
  appearance: none;
  width: 100%;
  margin-top: 1em;
}


/*For webkit browsers like chrome I have to include the following  pseudoelements.The third one is not useful here*/


/*The indicator*/

::-webkit-progress-value {
  background: linear-gradient(hsl(6, 100%, 80%), hsl(335, 100%, 65%));
  border-radius: 20px;
  position: relative;
  overflow: hidden;
}

::-webkit-progress-value::after {
  content: "";
  position: absolute;
  width: 20px;
  height: 20px;
  background: yellow;
  border-radius: 50%;

  border-radius: 20px;

  border: 2px solid hsla(229, 57%, 11%, 0.5);
}


/*for moz browsers like Firefox,I have to  use the only existing pseudoelement(one) for appearance property for it and style it the sam as i styled ::-webkit-progress-value,I could have used comma to separate the selectors but we are dealing with experimental properties and we have non-stadard behaviour */

::-moz-progress-bar {
  background: linear-gradient(hsl(6, 100%, 80%), hsl(335, 100%, 65%));
  border-radius: 20px;
}


/*End of experimental declarations*/

.left-storage {
  width: 175px;
  height: 75px;
  background: hsl(0, 0%, 100%);
  border-radius: 0.6em;
  margin-top: -2.35em;
}

.left-storage {
  display: flex;
  flex-direction: row;
  align-items: center;
  justify-content: center;
  gap: 12px;
}

.left-storage>span:nth-child(1) {
  font-weight: 700;
  font-size: 2.5rem;
  opacity: 0.9;
}

.left-storage>span:nth-child(2) {
  text-transform: uppercase;
  font-weight: 600;
  font-size: 0.8rem;
  color: hsla(229, 7%, 55%, .8);
}

  }
  .left-storage::before {
    content: "";
    position: absolute;
    right: 100%;
    top: 26px;
    width: 0;
    height: 0;
    border-top: 13px solid transparent;
    border-right: 26px solid white;
    border-bottom: 13px solid transparent;
  }
}

</main>

What I want to achieve is that the tail of the message-box (i.e .left-storage in the css) to be positioned as it is in the design. I want to understand how to do this.

I also want know how to make the small white circle appear at the end of progress-value (that loading thing) with css.

Update your HTML and CSS by this one and try, this might be you needing

I have solved the problem, please use the below CSS code:

* {
    margin: 0;
    padding: 0;
    box-sizing: border-box;
}
