To solve the overflow issue in CSS Flex layout, we will solve the following two examples -

Fix overflow - set height of outer div to always be equal to specific inner div
Avoid overflow when nesting elastic containers

Set the height of the outer div to always be equal to the specific inner div and fix the overflow issue

Example

We are using Flex to fix an overflow issue between inner and outer divs. Let’s see an example −

<!DOCTYPE html>
<html>
<head>
   <style>
   .outer {
      display: flex;
      border: 1px solid blue;
      padding: 5px;
      box-sizing: border-box;
   }
   .outer>div {
      flex: 1;
      margin: 5px;
      border: 1px solid;
      box-sizing: border-box;
   }
   div.inner {
      border-color:orange;
   }
   .inner-in {
      position: relative;
      overflow: auto;
   }
   .inner-in>div {
      position: absolute;
      top: 0;
      right: 0;
      left: 0;
      bottom: 0;
   }         
   </style>
</head>
<body>
   <h1 id="Adjusting-Inner-and-Outer-Div">Adjusting Inner and Outer Div</h1>
   <div class="outer">
      <div class="inner">In faucibus dictum mauris quis molestie. Nulla vestibulum ipsum eget pulvinar euismod. Fusce pulvinar volutpat scelerisque. Ut pretium commodo faucibus. </div>
      <div class="inner-in">
         <div>Vestibulum et mauris eleifend, ornare augue at, mattis lacus. Mauris aliquet viverra aliquam. Nunc ac nibh tempus, interdum libero in, pellentesque nisi.</div>
      </div>
      <div class="inner-in">
         <div>eget bibendum risus commodo. Nullam tristique nibh sed iaculis vulputate. 
         Vivamus ac tincidu. Pellentesque fringilla pulvinar orci, non dapibus tortor aliquam 
         vel. Aenean eget quam vel nisi malesuada auctor nec quis nunc. Morbi eu tempor nunc</div>
      </div>
   </div>
   <div class="outer">
      <div class="inner">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec 
      dignissim ipsum orci, io vestibulum, eget bibendum risus commodo. Nullam tristique nibh 
      sed iaculis vulputate</div>
      <div class="inner-in">

         viverra aliquam. Nunc ac nibh tempus, interdum libero in, pellentesque nisi. Nullam 
         tristique nibh sed iaculis vulputate. Vivamus ac tincidu</div>
      </div>
      <div class="inner-in">
         <div>eget bibendum risus commodo. Nullam tristique nibh sed iaculis vulputate. Vivamus ac tincidu</div>
      </div>
   </div>
   <div class="outer">
      <div class="inner">In faucibus dictum mauris quis molestie. Nulla vestibulum ipsum eget 
      pulvinar euismod. Fusce pulvinar volutpat scelerisque. Ut pretium commodo faucibus. 
      vestibulum, eget bibendum risus commodo. Nullam tristique nibh sed iaculis vulputate , 
      eget bibendum risus commodo. Nullam tristique nibh sed iaculis vulputate</div>
      <div class="inner-in">
         <div>Donec eget libero est. Vestibulum libero tellus, aliquam non mattis quis, 
         pellentesque eu quam. Duis laoreet scelerisque risus, elementum porttitor dui 
         tincidunt quis. Ut volutpat ligula finibus a. Maecenas ut pharetra ante. Nunc 
         volutpat est eu odio vestibulum, eget bibendum risus commodo. Nullam tristique nibh 
         sed iaculis vulputate. Vivamus ac tincidu</div>
      </div>
      <div class="inner-in">
         <div>eget bibendum risus commodo. Nullam tristique nibh sed iaculis vulputate. Vivamus ac tincidu</div>
      </div>

Avoid overflow problems when nesting elastic containers

There are two divs in our parent div ParentBox -

<div class='parentBox'>
   <div class='childBox'>
      <div class='babyChildBox'>Parent's Child</div>
      <div class='babyChildBox'>Parent's Child</div>
   </div>
   <! - - -
   !-->
</div>

The style of the parent container. We use CSS Flex shorthand properties -

.parentBox {
   display: flex;
   flex: 1 0 100%;
   background-color:yellow;
   border: 3px solid skyblue;
}

For the child element, that is, childBox, we again use the abbreviation attribute to set the elastic length of the elastic item -

.childBox {
   flex: 1 1 50%
   background-color: green;
   color: white;
   border: 1px solid blue;
}

The nested children in the .childBox above are set using Flex. This and above have nested Flex containers -

.babyChildBox {
   flex: 1 1 50%;
   background-color: orange;
}

Example

Now let's see a complete example of nesting flex containers correctly and trying to avoid overflow issues -

<!DOCTYPE html>
<html>
<head>
   <style> 
   .parentBox {
      display: flex;
      flex: 1 0 100%;
      background-color:yellow;
      border: 3px solid skyblue;
   }
   .childBox {
      flex: 1 1 50%
      background-color: green;
      color: white;
      border: 1px solid blue;
   }
   .babyChildBox {
      flex: 1 1 50%;
      background-color: orange;
   }
   </style>
</head>
<body>
   <h1 id="Implementing-Flex">Implementing Flex</h1>
   <div class='parentBox'>
      <div class='childBox'>
         <div class='babyChildBox'>Parent's Child</div>
         <div class='babyChildBox'>Parent's Child</div>
      </div>
      <div class='childBox'>
         <div class='babyChildBox'>Parent's Child</div>
         <div class='babyChildBox'>Parent's Child</div>
      </div>
   </div>
</body>
</html>

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
