Responsive text positioning? - html

Question

I use Bootstrap carousel slider with text (carousel-caption). It is responsive on all device, but the text is always centered and on the bottom of screen. I know how to position the text wherever I want.
But if I change the position, it isn't properly displayed on other devices. I just want to position the text to the left and in the middle of the screen and I want it to stay there when I resize the viewport.
.carousel-caption {
top: 35%;
width:500px;
left: 220px;
bottom: auto;
}
.red {
color:red;
}
.carousel-item {
height: 100vh;
min-height: 350px;
background: no-repeat center center scroll;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
.lnr {
display: inline-block;
fill: currentColor;
width: 1em;
height: 1em;
vertical-align: -0.05em;
stroke-width: 1;
}
.services-icon {
margin-bottom: 20px;
font-size: 30px;
}
bgc2, .vLine, .hLine {
background-color: #0F52BA;
}
.quote-icon {
font-size: 40px;
margin-bottom: 20px;
}
.services-icon {
font-size: 60px;
margin-left: 2rem;
}
.slide1-title {
font-size: 40px;
}
.slide1-content{
font-size:18px;
}
.btn-style-one {
position: relative;
padding: 14px 30px;
line-height: 1em;

Answer 1

For minimal change; replace your '.carousel-caption' style block with the below:
.carousel-caption {
top: 0 !important;
left: 0 !important;
width: 100%;
max-width: 100vw;
padding: 0 15%;
}
And add for that "I just want to put text left in the middle of the screen":
.carousel-caption .lead {
text-align: left;
position: absolute;
top: 45vh;
}

Answer 3

I am not sure if you want to center the text horizontally or vertically. So both answers:
Horizontally
The element you want to center .carousel-caption has a px width and margins in percentage.
You can either use percentage values only:
.carousel-caption {
width: 70%;
left: 15%;
}
or just make it full width, as all the contained text is centered:
.carousel-caption {
width: 100%;
left: 0px;
right:0px;
}
Vertically
.carousel-caption {
top: 50%;
bottom: auto;
transform: translateY(-50%);
}
