Text is breaking using absolute positioning

问题

I have a small challenge that I haven't found any solution on Stack Overflow.

That's what I got:

And that's how I'd like it:

To produce this title effect I'm using absolute position. I don't even know the width and the height from my title. So, big text breaks when using this solution.

My HTML:

<div class="content">
  <h1 class="title">February 2015</h1>
  <p>Mussum ipsum cacilds, vidis litro abertis. Consetis adipiscings elitis. Pra lá , depois divoltis porris, paradis. Paisis, filhis, espiritis santis. Mé faiz elementum girarzis, nisi eros vermeio, in elementis mé pra quem é amistosis quis leo. Manduma pindureta quium dia nois paga. Sapien in monti palavris qui num significa nadis i pareci latim. Interessantiss quisso pudia ce receita de bolis, mais bolis eu num gostis.</p>
</div>

My CSS:

.content {
  border: 3px double black;
  padding-top: 60px;
  position: relative;
  width: 350px;
}

.content p { margin: 20px; }

.title {
  background: black;
  border-radius: 5px;
  color: white;
  left: 50%;
  padding: 10px;
  position: absolute;
  text-align: center;
  transform: translate(-50%, -50%);
  top: 0;
}

The easiest solution would be to add white-space: nowrap. In doing so, the h1 text will not break to a new line. (updated example)

.title {
  white-space: nowrap;
  background: black;
  border-radius: 5px;
  color: white;
  left: 50%;
  padding: 10px;
  position: absolute;
  text-align: center;
  transform: translate(-50%, -50%);
  top: 0;
}

In addition, you could also add text-overflow: ellipsis/overflow: hidden/width: 100% so that the text forms ellipsis and never breaks to a new line. (example here)

Here, I have made a few minor CSS changes for you.

/* Cosmetics */
* { box-sizing: border-box; }
body { margin: 50px; }
p { margin: 0; }


/* True Code */
.content {
  border: 3px double black;
  padding-top: 30px;
  position: relative;
  width: 350px;
}

.content p { margin: 20px; }

.title {
  background: black;
  border-radius: 5px;
  color: white;
  left: 50%;
  padding: 10px;
  position: absolute;
  text-align: center;
  transform: translate(-50%, -50%);
  top: 0;
  white-space: nowrap;
  margin-top: 0px;
}

your code was correct but the left attribute spoiled your output. as your .content div was set to relative, the .title will remain inside it. So you just need to change the position your .title using transform: translate(); code. And voila you got your desired output.

You might notice i have given padding-top to the .content just to place the heading in a proper place.

the changed code is as follows :

/* Cosmetics */
* { box-sizing: border-box; }
body { margin: 50px; }
p { margin: 0; }


/* True Code */
.content {
  border: 3px double black;
  padding-top:10px;
  position: relative;
  width: 350px;
}

.content p { margin: 20px; }

.title {
  background: black;
  border-radius: 5px;
  color: white;
  padding: 10px;
  position: absolute;
  transform: translate(22%,-110%);
}

There is another solution:

.title {
    width: max-content;
}

It is widely supported (92.25% as of 17.07.2019) https://caniuse.com/#feat=intrinsic-width
