定位绝对定位的旋转文本

Question

I am having a really tough time positioning a transformed, rotated text. Both vertically and horizontally, I cannot figure out how to position the rotated text rotateText , so that it is bottom: 60px and left: 10% within the relative container #tslotBlock1inner .

Then if you click on the jsfiddle link below and alter the viewport for 640px or less, you will see that the rotated text completely goes away, even with left:30% .

I have included an image below of how I would like it positioned. Can anyone help and explain what I am doing wrong?

 .sec90 { width: 90%; margin: 20px auto 60px auto; } .rotateText { position: absolute; top: 50%; bottom: 60px; left: 2%; -webkit-transform: rotate(-90deg) translateX(-50%);transform: rotate(-90deg) translateX(-50%); font-family: 'Nunito', sans-serif; letter-spacing: .2rem; font-size: 2rem; color: #b82222; text-transform: uppercase; } #tslotSec { margin: 60px auto; } #tslotBlock1 { display: inline-block; vertical-align: top; } #tslotBlock1 { width: 70%; } #tslotBlock1:after { content: ''; display: inline-block; background: #b82222; width: 8px; height: 70%; vertical-align: middle; } #tslotBlock1inner { padding-right: 10%; position: relative; } #tslotBlock1inner img { width: 35%; height: auto; margin-left: 30%; } .dG { font-size: 1.1rem; line-height: 1.5em; font-family: 'Nunito', sans-serif; } /*---------------------------------------------- MEDIA QUERY 640 --------------------------------------------*/ @media screen and (max-width:640px) { .rotateText { bottom: 0px; left: 30%; -webkit-transform: rotate(-90deg) translateX(0%);transform: rotate(-90deg) translateX(0%); font-size: 1.5rem; } }

Answer 1

I prefer to avoid position: absolute; for elements that are part of a page's content, so I used float instead. I also set transform-origin since it's often easier to figure out positioning relative to a fixed point rather than the middle of an object's bounding box:

.rotateText {
    float: left;
    transform-origin: top left;
    -webkit-transform: rotate(-90deg) translateX(-100%);
    transform: rotate(-90deg) translateX(-100%);
    font-family: 'Nunito', sans-serif;
    letter-spacing: .2rem;
    font-size: 2rem;
    color: #b82222;
    text-transform: uppercase;
}

Answer 2

I got it by updating your transforms and removing the positioning

.rotateText {
position: absolute;
-webkit-transform: rotate(-90deg) translate(-100px, -100px);
transform: rotate(-90deg) translate(-100px, -100px);
font-family: 'Nunito', sans-serif;
letter-spacing: .2rem;
font-size: 2rem;
color: #b82222;
text-transform: uppercase;
}

Answer 3

I agree with DavidW. I added some positioning and a bottom attribute to keep the text down beside the image.

.rotateText {
    float: left;
    position: relative;
    bottom: 0px;
    transform-origin: top left;
    -webkit-transform: rotate(-90deg) translateX(-100%);
    transform: rotate(-90deg) translateX(-100%);
    font-family: 'Nunito', sans-serif;
    letter-spacing: .2rem;
    font-size: 2rem;
    color: #b82222;
    text-transform: uppercase;
}

This is kind of a different approach, but does not depend on magic numbers/sizes, using css writing-mode :

 .rotated-text { writing-mode: vertical-lr; transform: rotate(180deg); font-size: 60px; text-transform: uppercase; display: inline-block; background: cyan; } .flex { display: flex; } .image { flex-grow: 1; background: url(https://boygeniusreport.files.wordpress.com/2016/11/puppy-dog.jpg?quality=98&strip=all&w=782); background-position: center; background-repeat: no-repeat; background-size: contain; }
