How to place two divs next to each other?

Answer 1

#wrapper {
width: 1200;
border: 1px solid black;
position: relative;
float: left;
}
#first {
width: 300px;
border: 1px solid red;
position: relative;
float: left;
}
#second {
border: 1px solid green;
position: relative;
float: left;
width: 500px;
}

<div id="wrapper">
    <div id="first">Stack Overflow is for professional and enthusiast programmers, people who write code because they love it.</div>
    <div id="second">When you post a new question, other users will almost immediately see it and try to provide good answers. This often happens in a matter of minutes, so be sure to check back frequently when your question is still new for the best response.</div>
</div>

Answer 3

here is the solution:

#wrapper {
    width: 500px;
    border: 1px solid black;
    overflow: auto; /* so the size of the wrapper is alway the size of the longest content */
}
#first {
    float: left;
    width: 300px;
    border: 1px solid red;
}
#second {
    border: 1px solid green;
    margin: 0 0 0 302px; /* considering the border you need to use a margin so the content does not float under the first div*/
}

This is the right CSS3 answer. Hope this helps you somehow now :D I really recommend you to read the book: https://www.amazon.com/Book-CSS3-Developers-Future-Design/dp/1593272863 Actually I have made this solution from reading this book now. :D

#wrapper{
  display: flex;
  flex-direction: row;
  border: 1px solid black;
}
#first{
  width: 300px;
  border: 1px solid red;
}
#second{
  border: 1px solid green;
}

<div id="wrapper">
    <div id="first">Stack Overflow is for professional and enthusiast programmers, people who write code because they love it.</div>
    <div id="second">When you post a new question, other users will almost immediately see it and try to provide good answers. This often happens in a matter of minutes, so be sure to check back frequently when your question is still new for the best response.</div>
</div>

Option 1

Use float:left on both div elements and set a % width for both div elements with a combined total width of 100%.

Use box-sizing: border-box; on the floating div elements. The value border-box forces the padding and borders into the width and height instead of expanding it.

Use clearfix on the <div id="wrapper"> to clear the floating child elements which will make the wrapper div scale to the correct height.

.clearfix:after {
   content: " "; 
   visibility: hidden;
   display: block;
   height: 0;
   clear: both;
}

#first, #second{
  box-sizing: border-box;
  -moz-box-sizing: border-box;
  -webkit-box-sizing: border-box;
}

#wrapper {
    width: 500px;
    border: 1px solid black;
}
#first {
    border: 1px solid red;
    float:left;
    width:50%;
}
#second {
    border: 1px solid green;
    float:left;
    width:50%;
}

Option 2

Use position:absolute on one element and a fixed width on the other element.

Add position:relative to <div id="wrapper"> element to make child elements absolutely position to the <div id="wrapper"> element.

#wrapper {
    width: 500px;
    border: 1px solid black;
    position:relative;
}
#first {
    border: 1px solid red;
    width:100px;
}
#second {
    border: 1px solid green;
    position:absolute;
    top:0;
    left:100px;
    right:0;
}

Option 3

Use display:inline-block on both div elements and set a % width for both div elements with a combined total width of 100%.

And again (same as float:left example) use box-sizing: border-box; on the div elements. The value border-box forces the padding and borders into the width and height instead of expanding it.

NOTE: inline-block elements can have spacing issues as it is affected by spaces in HTML markup. More information here: https://css-tricks.com/fighting-the-space-between-inline-block-elements/

#first, #second{
  box-sizing: border-box;
  -moz-box-sizing: border-box;
  -webkit-box-sizing: border-box;
}

#wrapper {
    width: 500px;
    border: 1px solid black;
    position:relative;
}

#first {
    width:50%;
    border: 1px solid red;
    display:inline-block;
}

#second {
    width:50%;
    border: 1px solid green;
    display:inline-block;
}

A final option would be to use the new display option named flex, but note that browser compatibility might come in to play:

In material UI and react.js you can use the grid

<Grid
  container
  direction="row"
  justify="center"
  alignItems="center"
>
    <Grid item xs>
      <Paper className={classes.paper}>xs</Paper>
    </Grid>
    <Grid item xs>
      <Paper className={classes.paper}>xs</Paper>
    </Grid>
    <Grid item xs>
      <Paper className={classes.paper}>xs</Paper>
    </Grid>

</Grid>
