Center Icon

[veragreen119]

I am following the code in this example: https://labs.easyblog.it/maps/leaflet-panel-layers/examples/collapsible-panel.html

It is all working and I was also able to use a glyphicon instead of a saved icon. My issue is that I can not get the icons (either from file or glyphicon source) to center in the collapsed window. Any advice?

Relevant sections of code attached. I tested the CSS in JFiddle and it correctly places the icon at the center of the box so it must be that the box is not centered.

I was just pondering this and realized the + and - symbol is also not centered. See comparison screenshot. I'm using Leaflet 1.5.1 - but not related to that, same issue with 1.4/1.3. Issue is related to bootstrap library being present in my map. comparison_screenshot.zip

To adjust the alignments of icons you need to edit the style sheet mainly so that the minimum size is such that the icon is still in the button. I made a few changes to leaflet-panal-layers.css to fix this bellow yo8u can see an updated version with a few comments by what was changed. I couldn't get the vertical alignment of text to work properly as it seams to be in its own span. but it is in the right spot.

This works. thanks.
To get a bit more space between the icon and the check box:

.leaflet-panel-layers-icon {
    line-height: 20px;
    display: inline-block;
    height: 20px;
    width: 20px;
    padding: 3px;/*adding padding here makes the icons 32x32*/
    background: #fff;
    padding-right: 25px;/*adding padding here creates some space between the icon and the label*/
}

Still looking for a way to get a bit of space between the checkbox and the label.This might require adding a css class.

The issue was actually with bootstrap applying a global rule which effected the menus to fix it load the fallowing css after loading bootstrap this will override the offending css rules everywhere.

<style type="text/css" >
    *{
        -webkit-box-sizing: unset;
        -moz-box-sizing: unset;
        box-sizing: unset;
    }
</style>

if they are needed for other bootstrap features the following rules seem to fix the issue for just this plugin

 .leaflet-panel-layers-group {
        -webkit-box-sizing: unset;
        -moz-box-sizing: unset;
        box-sizing: unset;
    }
    .leaflet-panel-layers-item {
        -webkit-box-sizing: unset;
        -moz-box-sizing: unset;
        box-sizing: unset;
    }
    .leaflet-panel-layers{
        -webkit-box-sizing: unset;
        -moz-box-sizing: unset;
        box-sizing: unset;
    }
