"Enhance Your HTA Webpage with a Hover Zoom Effect on CSS Tables

Greetings and thank you for taking the time to read my message. I am relatively new to this, so please bear with me if things seem a bit disorganized.

I have constructed a table and am attempting to implement a hover effect to zoom in on a specific cell without disturbing the position of the surrounding cells. Ideally, I would like the zoomed-in view to be centered rather than expanding from the upper left corner. Below is an excerpt from the CSS styling used for this purpose. Currently, when I hover over a cell, it not only enlarges but also shifts everything to the right. My goal is for the zooming action to preserve the layout of other cells on the table. If additional information is needed, please do let me know. It's worth mentioning that all this coding pertains to an HTA (HTML Application) and certain functionalities might be limited within this environment. Thank you!

Answer №1

To achieve scaling in modern browsers, CSS3 can be used with the transform:scale(1.5) property. However, for older browsers or when using mshta.exe in HTA, a more complex approach may be necessary.

If simply specifying 

<meta http-equiv="x-ua-compatible" content="ie=9">
(and potentially also <!DOCTYPE html>) doesn't resolve the issue, additional code to support pre-IE9 versions can be implemented:

/* IE8+ */
-ms-filter: "progid:DXImageTransform.Microsoft.Matrix(M11=1.5, M12=0, M21=0, M22=1.5, SizingMethod='auto expand')";

/* IE6 and 7 */ 
filter: progid:DXImageTransform.Microsoft.Matrix(
        M11=1.5,
        M12=0,
        M21=0,
        M22=1.5,
        SizingMethod='auto expand');

/* "\9" is a fix to target only IE versions before IE9 */
margin-left: -64px\9; 
margin-top: -9px\9;

Optimizing your code can lead to cleaner results:

Avoid repeating styles by utilizing CSS cascading behavior. Instead of distinct button1 and button2 classes, consider using a generic button class with additional classes like red and blue.

By incorporating these adjustments, you can enhance the design aesthetics. Check out an example here.

.button {
    /* Styles */
}
.button:hover {
    /* Hover effects */
}

.blue {
    color: blue;
}
.red {
    color: red;
}

Addressing inadequacies in HTA compatibility might require a javascript fallback solution, as seen in this revised approach:

// Custom function for browser support
if (!supports('transform')) {
    // Button scaling on hover
    for(var i = 0; i < buttons.length; i++) {
        buttons[i].onmouseover = function() {
            scale(this, 1.5);
        }        
    }
}

function scale(obj, scaleFactor) {
    /* Scaling logic */
}

function unscale(obj) {
    // Reverting scaled changes
}

The custom pseudo-scale implementation in pure javascript showcases creativity. Detailed comments aid in understanding the functionality.

After implementing these enhancements, hopefully, your challenges are resolved satisfactorily!

Would you be open to utilizing CSS3? Below is a demonstration on JSFiddle showcasing CSS3 in action along with the corresponding code snippet. I have streamlined the code by removing unnecessary CSS properties (e.g., .button1:hover retains the same settings as .button1).

Link to the example

.button1 {
    display: inline-block;
    position: relative;
    color: red;
    width:245px;
    height:25px;
    font-family: Tahoma;
    font-size: 12px;
    text-align:center;
    text-decoration: none;
    background-color: #E2E2E2;
    border-top: 2px solid #F1F1F1;
    border-right: 2px solid #969696;
    border-bottom: 2px solid #969696;
    border-left: 2px solid #F1F1F1;
    z-index: 1;
}
.button1:hover {
    -webkit-transform:scale(1.6);
    -moz-transform:scale(1.6);
    -ms-transform:scale(1.6);
    -o-transform:scale(1.6);
    transform:scale(1.6);
    z-index: 2;
}
.button2 {
    display: inline-block;
    position: relative;
    width:245px;
    height:25px;
    font-family: Tahoma;
    font-size: 12px;
    text-align:center;
    text-decoration: none;
    background-color: #E2E2E2;
    border-top: 2px solid #F1F1F1;
    border-right: 2px solid #969696;
    border-bottom: 2px solid #969696;
    border-left: 2px solid #F1F1F1;
    z-index: 1;
}
.button2:hover {
    -webkit-transform:scale(1.6);
    -moz-transform:scale(1.6);
    -ms-transform:scale(1.6);
    -o-transform:scale(1.6);
    transform:scale(1.6);
    z-index: 2;
}

After a collaborative effort from everyone involved and following the link provided by Teemu, I was able to successfully resolve the issue. Surprisingly, it turned out that simply including the !DOCTYPE and meta tag in the correct places did the trick. Many thanks to all for your support! Below is the revised code that is now working:

<!DOCTYPE html>
<HTML>
  <HEAD>
    <TITLE>Menu</TITLE>
    <meta http-equiv="x-ua-compatible" content="ie=9">  
    <HTA:APPLICATION ID = "AppMenu"
        APPLICATIONNAME = "AppMenu"
        border="thick"
        scroll="no" 
        singleinstance="no"
        showintaskbar="yes"
        windowstate="Normal"
        innerBorder="no"
    >
<Script>
</Script>

</HEAD>
 <style text="text/CSS">
.button {
    width:245px;
    height:15x;
    display:inline-block;
    font-family: Tahoma;
    font-size: 12px;
    text-align:center;
    text-decoration: none;
    background-color: #E2E2E2;
    border-top: 2px solid #F1F1F1;
    border-right: 2px solid #969696;
    border-bottom: 2px solid #969696;
    border-left: 2px solid #F1F1F1;
}
.button:hover {
    -webkit-transform:scale(1.5);
    -moz-transform:scale(1.5);
    -ms-transform:scale(1.5);
    -o-transform:scale(1.5);
