text comes out of the container when I write long text (without space)-CodePudding

If I write a long sentence the text doesn't fit the container. Why does the text overflow the container?

But when I write a long sentence but use spaces (write more than 1 sentence), the text finally fits the container.

<p>no spaces:</p>
<div style="height:50px;width: 200px;border: 4px solid red;">helloooooooooooooooooooooooooooooooo</div>
<br>
<p>with spaces:</p>
<div style="height:50px;width: 200px;border: 4px solid red; ">hello ooooooo ooooo ooooooo ooooooooo oooooooo</div>

To break the line of your text you can use overflow-wrap: break-word;:

<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">

<body>
  <p>no spaces:</p>
  <div style="height:50px;width: 200px;border: 4px solid red;overflow-wrap: break-word;">helloooooooooooooooooooooooooooooooo</div>
  <br>
  <p>with spaces:</p>
  <div style="height:50px;width: 200px;border: 4px solid red;
  ">hello ooooooo ooooo ooooooo ooooooooo oooooooo</div>
</body>
</html>

Please find below the new styling that I added -> word-wrap: break-word; This makes the word break and fit the box size.

<p>no spaces:</p>
<div style="height:50px;width: 200px;border: 4px solid red; word-wrap: break-word;">helloooooooooooooooooooooooooooooooo</div>
<br>
<p>with spaces:</p>
<div style="height:50px;width: 200px;border: 4px solid red; ">hello ooooooo ooooo ooooooo ooooooooo oooooooo</div>

By default, the UserAgent (default stylesheet of the browser) will not randomly break a word into multiple lines. The default setting is word-break: normal.

That means that a line-break will only appear on white-spaces, dashes, and line break opportunities (<wbr> tag).

Alternativly, you can allow a browser to break words at any point to fit the container by using: word-break: break-all:

div {
  word-break: break-all;
}

  <div style="height:50px;width: 200px;border: 4px solid red;
  ">hello ooooooo ooooo ooooooo ooooooooo oooooooo</div>
