Size Image To Fit Window (without Cropping Or Changing Ratio)

Oct 19, 2011

I'm trying to size an image to fit the browser window. It will be the only thing in the frame, so it doesn't matter if it's the background or not. I've found quite a few ways to have the image automatically resize itself where it either gets cropped off or changes ratio to stretch, but I've not found anything where it'll keep the full image and ratio and just have bars top and bottom or sides.

Accessibility: Possible To Determine Browser-chosen Point Size Of A Relative Font-size?

Jul 23, 2005

All my font-sizes are set as relative sizes in CSS (large, medium, small,
x-small, etc). Let's say something is set in CSS to be xx-large, but a
visually impaired user wants it displayed even bigger. Can a script
determine an element's absolute size, *as it is being rendered by the
browser*, and then increment the element's font-size in absolute terms?

Change Font Size Of #s In Address?

May 21, 2009

I operate as a admin a online print site where clients can enter in contact info to create imprint on promotional items.

I create pdf templates with field placeholders |1.1|[address]

This template is uploaded to the print site which interprets the tags and makes them into variable fields for clients to enter in their info. The site can pull the font name, size, position, etc... from the pdf template.

For each info field that the site creates it also has an option to apply javascript to that field. So if the template predefines font size X, I just want to apply code that will affect only the numbers of that text and make the numbers a larger font size than the letters.

The code I'm use to writing is pretty simple stuff for example to format dots instead of dashes for phone numbers like:

if (hasValue(curInput.name))
{
if (! AutoFormat(curInput, '###.###.####', 'Please enter your number in a 555.555.5555 format'))curInput.focus();
}

Change Font Size Mid Line?

Nov 7, 2009

I want to deviate from using css to designate a font size in one place.

I have a string with a name.

This is stored in a variable called "name."

I just re-defined name to include district number.

Now, it is name=lastname+', '+district;

I am appending this string into the html dom.

I want the district portion to appear in a slightly smaller font.

How can I do this without having to set up a separate <span>? Or can this be done?

Change Font-size When Opera Detected?

Oct 7, 2009

I need to get JavaScript to change the font size used for a website if Opera is detected. I have been trying this but it hasn't worked:

function changeFooter(){
if (navigator.userAgent.indexOf("Opera") >= 0) { // if I alert this line the output is 0
document.getElementById("footer").style.fontSize = '0.5em';
};

[Code].....

I was hoping that I could benefit from your collective wisdom as I am not sure where I am going wrong with this and several hours spent searching the web for answers have been fruitless so far...

My knowledge of JavaScript is not very extensive, I haven't studied it in great depth so perhaps I am making some very silly mistakes here.

My pseudo code for this exercise is something like this:

detect browser
if browser = Opera {
change font-size for body to 90%
}

[Code]....

Allow Users To Change The Font Size AND Family

Mar 18, 2007

I've seen dozens of scripts, some in javascript, some in php, that will allow you to do one or the other. Has anyone run across a script that has three buttons/images/links that will let you increase the font size, decrease the font size and switch font families? Either JS or php will suffice.

Event Listener For Browser Font Size Change

Aug 20, 2006

The problem:

I have an XHTML STRICT page which has some event listeners attached for onload and resize. I'm doing a bit of Javascript DHTML on these events. When a user changes the browser font size, the javascipt function needs to run. Although the TOPMENU DIV gets resized when the font changes size, its not a page resize so the function doesn't get run. I fixed this in IE6 by using a second function which is run onload and sets an event on the div object in the page after its been defined.

Problem is this doesn't work in Firefox.

Mozilla DOM reference says there is no resize event on a DIV so is there a work around to make it work in FIREFOX? i.e. can I force a resize event to happen on a div in firefox or is there some other event I can trap when a user changes the browser font size?

here's my js code: topmenu is what I'm trying to trap the resize event from.

this code is loaded in the head of the page.

function maindiv(){
estartup=document.getElementById("startup");
econtain=document.getElementById("contain");
emain=document.getElementById("main");
etopmenu=document.getElementById("topmenu");
emaincontent=document.getElementById("maincontent");
nopx = document.childNodes ? 'px' : 0;
contw = document.body.clientWidth - 80;
conth = document.body.clientHeight - 80;
if (contw < 0) { contw = 0;}
if (conth < 0) { conth = 0;}
econtain.style.width = contw+nopx;
econtain.style.height = conth+nopx;
if (conth >= 100 + etopmenu.clientHeight) {
emain.style.height = (conth - etopmenu.clientHeight - 100 )+nopx;
}
if (contw >= 172) {
emaincontent.style.width = (contw - 172 )+nopx;
}
estartup.style.visibility = 'hidden'
}


function fsize() {
etm=document.getElementById("topmenu");
if (typeof window.addEventListener != 'undefined')
{
etm.addEventListener("resize", maindiv, false);
}
else if (typeof document.addEventListener != 'undefined')
{
etm.addEventListener("resize", maindiv, false);
}
else if (typeof window.attachEvent != 'undefined')
{
etm.attachEvent("onresize", maindiv);}
else
{
window.alert('Failed to attach an Event Listener

Please Report');
}
}

if (typeof window.addEventListener != 'undefined')
{
window.addEventListener("load", maindiv, false);
window.addEventListener("load", fsize, false);
window.addEventListener("resize", maindiv, false);
}
else if (typeof document.addEventListener != 'undefined')
{
document.addEventListener("load", maindiv, false);
document.addEventListener("load", fsize, false);
document.addEventListener("resize", maindiv, false);
}
else if (typeof window.attachEvent != 'undefined')
{
window.attachEvent("onload", maindiv);
window.attachEvent("onload", fsize);
window.attachEvent("onresize", maindiv);
}
else
{
window.alert('Failed to attach an Event Listener

Please Report');
}

Any clues?

How To Get Window Size (not Viewport Size)

Apr 6, 2010

I'd have thought this would be easy but I've been looking for hours and all I can find is info on getting the viewport size, which is normally useful but not in my situation.

In this case I need the actual browser size, including the scrollbars, toolbars, status bars etc. to get an idea of browsers which aren't maximised/full screen and how big they are, and to calculate the amount of the screen taken up by toolbars etc too.

Swap Image Has Wrong Aspect Ratio

Jan 29, 2006

I am building a site in Dreamweaver for a client which uses templates
for a photogallery that uses simple Javascript to load images "OnClick"
into a named <img> tag. The <img> tag has no dimensions preset because
the loaded images vary in size and aspect ratio (the images
are all prepared so that they will fit easily within the rest of the page
layout, using their actual dimensions).

This all works just fine on Firefox (Apple), but on Safari and Mac IE
there is a problem. When image-2 replaces image-1 (using MM_swapimage),
if image-2 has the same height but a narrower width than image-1, then
image-2 appears with image-1's width. Both image-2 and image-1 have
the same height, so the display of image-2 now has the wrong aspect
ratio (everthing looks "fatter").

I haven't checked Windows browsers yet. I searched around and
haven't seen a similar issue. Anyone know about this, and a good workaround?
