Hi again everyone!

I am trying to find out where to look to find out how to make my pages adjust to the viewer's screen size. Everyone has different screen-sizes and they all have mobile phones too. I thought I knew how to do it, but I seem to have lost some gray matter along life's road.

If you can help with advice, I will be eternally grateful.

Detecting device screen size is a bad idea. Look up responsive design, the technique of making pages flexible.

 

In general, use percentage widths instead of pixels and use media queries to rearrange elements on screens that are too small to have elements side by side.

Thanks a Million!

That is exactly what I needed! And it can be done using only HTML and CSS. This is great! Thank you again,

John :)

sorry but this is what you are looking for-

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

add the above line to your <head> section. The page will adjust when you resize.

Well... I'm beginning to think that I'm just so far "out there" that I'd be pulling my hair out if I had any.

I've been trying everything I can find on making my background image fit the screen fully and not go over the screen or under the screen size. ( responsive design ) It may be time for basket-weaving!

At any rate, here is the mess that I'm trying to un-tangle.

( does the size of the image I'm using mean anything? )

As I said, I'm beginning to "lose it".

If you can tell me where to find the answer, that would be a true gift!

I don't know if this is partial code what but you have missing closing tags for div, body, html and the center tag which is not used anymore. Transitional doctype is old too, use html5 doctype, you have title outside head element when it should be within, and lastly two meta tags of name 'viewport' when there should be only one.

 

I suggest you learn basics of doctype and the correct layout of the main elements that make up a html document, and learn to validate using w3c validator.

Oh, no. Your page is very out of date. Drop the HTML 4.01 Transitional DOCTYPE. Here's an HTML 5 template:

<!DOCTYPE html>
<html>
  <head>
    <title>Website title</title>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <link rel="stylesheeet" href="style.css">
  </head>
  <body>
    Page content goes here
  </body>
</html>

You should have a CSS file to style the page. Read about CSS here: http://www.w3schools.com/css/default.asp

Tags like <center> and <font> don't exist, attributes such as bgcolor and align don't exist. CSS takes care of all of that.

 

For a solution to your immediate query, you can use the background-size property. Setting it to "cover" or "contain" will work. Read about the background-size property here: http://www.w3schools.com/cssref/css3_pr_background-size.asp

OK! I am going to give up and go back to the starting point and assume that everything that I thought I knew is either out-dated or invalid.

I reckon it's just what I need instead of confusing myself with bit's and pieces, not knowing for sure how they work and what I'm doing.

It's humbling, but I'm wasting my time and yours.

Thank you very much for the advice you've freely given me and showing me that I need understand the basics before I can just "copy code online and try to alter it myself" without knowing what it is doing!

I'm sure that I'll wind up asking for advice again at sometime in the future, though.

I'm beginning right here...http://www.w3schools.com/html/default.asp

Thanks again for pointing me in the right direction, that's what I asked for!

John :fool::D
