Tips for utilizing the viewport to ensure that mobile devices adjust to the width of the content

Currently, I am designing a book reader where the width of the book can vary, ranging from 1028px to 2000px to 560px.

I want mobile devices to automatically scale the book to fit the screen width when viewing it.

This is what I have been doing so far with an example book that has a width of 1028px and a height of 1648px:

In the head:

<meta name="viewport" content="width=1028"/>

In the stylesheet:

body { margin:0; padding:0; }
.bz { margin:0; padding:0; overflow:none; width:1028px; }
.pz { width:1028px; height:1648px; position:relative; }

The structure of the body is as follows:

<div class="bz">
   <div class="pz">
     Page 1 content
   </div>
   <div class="pz">
     Page 2 content
   </div>
   <div class="pz">
     Page 3 content
   </div>
</div>

Although this arrangement stacks the pages vertically, there are two issues:

  1. On mobile devices, the content does not fit perfectly on the screen, requiring horizontal scrolling. The zoom level is not ideal for the device screen width.

  2. Mobile users will notice excessive white space to the right with a horizontal scrollbar that allows them to scroll unnecessarily. This discrepancy is absent in desktop browsers, which disable horizontal scrolling if the window size exceeds the content width.

I believe I may be missing something in my design approach. Do you have any suggestions or solutions?

Thank you!

Answer №1

not the right approach in my view.

the optimal method for handling responsiveness is

<meta name="viewport" content="width=device-width, initial-scale=1.0">

if you want to enhance readability of the content, consider adjusting font-size rather than screen-size or "container" size.

you could utilize em units or rem units and modify the relative size of your entire reading experience by changing just one value: font-size in body.

by default 1em = 16px = 100% - so you can start with:

body {
    font-size:100%
}

with javascript, you can alter that value to be larger or smaller, causing your entire content's font-size to scale accordingly.

Answer №2

Give this a shot

<meta name="viewport" content="width=device-width, initial-scale=1">

swap it out with...

<meta name="viewport" content="width=1028"/>

I want the book to adjust automatically on mobile devices so that it always fits the screen width.

If you'd like the width to adapt based on screen size, delete width:1028px; from your css. Currently, it's instructing the book to stay at a fixed width without resizing according to the device screen.
