Customize slider

[Josiane212]

Hi,

I’d like to customize a slider for an experiment, the default one does not fit what I need.
I saw on another forum post that the best way to do so is with CSS magic.

        newScale("Main_Slider", 100)
            .slider()
            .css({"max-width" : "none", "width" : "400px", "height" : "100px"})
            .center()
            .print()
            .log()

I’m able to change the width with .settings.css, but I can’t change the color of the slider, the handle and other things like that.
When I’m modifying the PennController.css file to make it work (by copy-pasting parts of the w3schools code), nothing seems to apply to the slider. I tried changing .slider to the name of my element .Main_Slider but still nothing changes.

I’m quite new to javascript and css, so any help is appreciated! Thank you very much 🙂

Hi,

If you haven’t read it yet, I recommend you take look at this guide: Adding custom CSS

However the code I use to parse CSS at the PCIbex Farm has some bugs, so it’s often a better idea to edit global_main.css directly rather than relying on PennController.css automatically prefixing class names with PennController-. Another tricky thing is that when generating class names from element names, PennController will drop all underscores (_) so your Scale element’s CSS class name will be MainSlider, not Main_Slider

Here is what I added to global_main.css to get the desired rendering:

.PennController-MainSlider {
  width: 100%; /* Width of the outside container */
}

/* The slider itself */
.PennController-MainSlider input {
  -webkit-appearance: none;  /* Override default CSS styles */
  appearance: none;
  width: 100%; /* Full-width */
  height: 25px; /* Specified height */
  background: #d3d3d3; /* Grey background */
  outline: none; /* Remove outline */
  opacity: 0.7; /* Set transparency (for mouse-over effects on hover) */
  -webkit-transition: .2s; /* 0.2 seconds transition on hover */
  transition: opacity .2s;
}

/* Mouse-over effects */
.PennController-MainSlider input:hover {
  opacity: 1; /* Fully shown on mouse-over */
}

/* The slider handle (use -webkit- (Chrome, Opera, Safari, Edge) and -moz- (Firefox) to override default look) */
.PennController-MainSlider input::-webkit-slider-thumb {
  -webkit-appearance: none; /* Override default look */
  appearance: none;
  width: 25px; /* Set a specific slider handle width */
  height: 25px; /* Slider handle height */
  background: #04AA6D; /* Green background */
  cursor: pointer; /* Cursor on hover */
}

.PennController-MainSlider input::-moz-range-thumb {
  width: 25px; /* Set a specific slider handle width */
  height: 25px; /* Slider handle height */
  background: #04AA6D; /* Green background */
  cursor: pointer; /* Cursor on hover */
}

Let me know if you have questions

Thank you so much! It works perfectly 🙂

Hello,
I have a similar problem. I want to increase the width of a few slider elements. I have tried several methods including the ones discussed here, but nothing so far has increased the width of the slider beyond ~160 pixels.
I tried setting the width of the elements themselves with different units (%, px, in, cm), I tried editing the global_main.css and slider.css, and even the Scale.js module, but none of these had an effect.

What’s the most reliable way of increasing the width of a slider scale element?

Thanks

Matthias

Hello Matthias,

It would be easier to assist you with a link to your project. The most reliable way of increasing the width of a slider scale element is to use CSS rules in a CSS file named global_*.css in the project’s Aesthetics folder, as described on this thread. To overwrite the constraint on the slider’s maximum length that PennControler sets by default, add max-width: unset !important; to the CSS rules that apply to the Scale element (.PennController-MainSlider in the example above)

Hello Jeremy,
I have solved this problem in the meantime. The solution was to simply include “max width”: “none” in the css settings of the element in the main script:

newScale("Originell", 100)
            .slider()
            .settings.css({
                "max-width" : "none",
                "width": "450px",
                "margin": "auto",  
                "align": "center",
                "text-align": "center"
                })
            .before(newText("label3", "gar nicht   "))
            .after(newText("label4", "   perfekt"))
            .center()
            .print()
            .log()
