Div tag border with title - css

Question

I need to display a border around a div tag with a title in the border itself. In order to do this, this is what I have come up with so far
.componentWrapper {
border: solid cadetblue;
border-radius: 40px;
padding: 10px;
width: 95%;
}
.componentTitle {
font-size: 18px;
width: 15%;
background-color: white;
margin-top: -25px;
}
<div class='componentWraper'><p class='componentTitle'>This is the title</p>This is the component body text</div>
As you can see I am using margin property to push the title up on top of the border. I am not sure if this is the proper approach to do this and I have the following questions.
I am positioning the title using pixels (margin) and a fixed value (-25px). This is a site that has to work on mobile phones, tablets as well. Is this an acceptable approach?
I am setting the background-color to white so that the border does not appear behind the text, is this an ok approach?
Is there a better and more acceptable way to do this, I do not want to use fieldset because we have little control over the border (border-radius).

Answer 1

There are three logical ways you can use to achieve this.
You can use a <fieldset> with a legend which is the basic HTML way of doing this. You can find more information about this here.
Use custom CSS with positioning, not negative margins or etc.:
body {
background: #fff;
}
.componentWraper {
margin: 40px; /* just for contrast */
position: relative;
border: 2px solid tomato;
border-radius: 12px;
padding: 20px;
}
.componentWraper .componentTitle {
position: absolute;
top: -25px;
background: #fff;
padding: 0 10px;
}
<div class='componentWraper'>
<p class='componentTitle'>This is the title</p>This is the component body text</div>
Use custom CSS with pseudo-elements:
body {
background: #fff;
}
.componentWraper {
margin: 40px; /* just for contrast */
position: relative;
border: 2px solid tomato;
border-radius: 12px;
padding: 20px;
}
.componentWraper::before {
content: 'This is the title';
position: absolute;
top: -10px;
padding: 0 10px;
background: #fff;
}
<div class='componentWraper'>This is the component body text</div>

I think you're on the right track. I'd make a few changes to have more control over the styling. You can use ems or pixels.
Wrap the title and content in a new div and give that a negative margin:
<div class='componentWrapper'>
<div>
<div class='componentTitle'>This is the title</div>
<div class='componentContent'>
<p>This is the component body text</p>
</div>
</div>
.componentWrapper div {
margin-top: -1em;
}
Set your title to display: inline-block and use padding to control the white space around it (instead of using width)
.componentTitle {
font-size: 18px;
background-color: white;
display: inline-block;
padding: .5em;
}
codepen
snippet:
.componentWrapper {
border: solid cadetblue;
border-radius: 40px;
padding: 10px;
width: 95%;
margin-top: 1em;
}
.componentWrapper div {
margin-top: -1.2em;
}
.componentTitle {
font-size: 18px;
background-color: white;
display: inline-block;
padding: .5em .3em;
}
<div class='componentWrapper'>
<div>
<div class='componentTitle'>This is the title</div>
<div class='componentContent'>
<p>This is the component body text</p>
</div>
</div>

This is what I came up with. I wanted to get rid of the negative margin, but couldn't figure out a way to do that.
See the Pen offset title by Yvonne Aburrow (#vogelbeere) on CodePen.
HTML
<div class="componentWrapper">This is the component body text</div>
CSS
.componentWrapper {
border: 1px solid blue;
border-radius: 40px;
padding: 16px;
width: 95%;
margin: 3em;
}
.componentWrapper:before {
content: "this is the title";
font-size: 18px;
width: 10%;
background-color: white;
border: 1px solid blue;
border-radius: 12px;
display: block;
margin-top: -29px;
padding: 3px;
}
I am not sure how a screen reader would deal with the title text being in the CSS (or how you would scale that up if you have a lot of different titles.
