Having trouble adjusting the vertical position of jQuery Spinner buttons

I'm attempting to customize the jQuery spinner with styling applied like this:

<span class="ui-spinner ui-widget ui-widget-content ui-corner-all" style="height: 14px;">
<input id="testSpinner" class="ui-spinner-input" name="value" aria-valuemin="9" aria-valuemax="1550" autocomplete="off" role="spinbutton" aria-valuenow="9"></input>
    <a class="ui-spinner-button ui-spinner-up ui-corner-tr" tabindex="-1"></a>
    <a class="ui-spinner-button ui-spinner-down ui-corner-br" tabindex="-1"></a>
</span>

My goal is to stack the two buttons, however, I'm facing difficulty in moving the "up" button up and the "down" button down. I have successfully shifted the down button left by overriding the ui-spinner-down class and setting margin-left: -3.2rem, but adjusting margin-top / margin-bottom has not yielded results.

As jQuery defines the height: 14px; within the span tag, modifying that value proves to be a challenge as well.

Current Status:

Desired Outcome:

Answer №1

It is recommended to use margin-top and margin-bottom instead of margin-up and margin-down

To replace the style attribute, you can specify the height using "!important"

height: 10px !important;

If margin isn't effective, consider using position: relative; top: 10px where "10px" can be adjusted to position the button correctly.

Ensure to adjust the padding or line-height for proper centering of the arrow within the specified height.

Note that jQuery's border-radius should be set to 0 on the right side of the input and left side of the buttons. Additionally, apply border-left: 0 to the buttons and border-top: 0 to the bottom button.

Answer №2

Here is the code snippet generated from the jQuery spinner demo.

<span class="ui-spinner ui-widget ui-widget-content ui-corner-all">
    <input id="spinner" class="ui-spinner-input" name="value" aria-valuenow="6" autocomplete="off" role="spinbutton">
    <a class="ui-spinner-button ui-spinner-up ui-corner-tr ui-button ui-widget ui-state-default ui-button-text-only" tabindex="-1" role="button">
      <span class="ui-button-text">
        <span class="ui-icon ui-icon-triangle-1-n">▲</span>
      </span>
    </a>
    <a class="ui-spinner-button ui-spinner-down ui-corner-br ui-button ui-widget ui-state-default ui-button-text-only" tabindex="-1" role="button">
      <span class="ui-button-text">
        <span class="ui-icon ui-icon-triangle-1-s">▼</span>
      </span>
    </a>
</span>

The CSS styles associated with it are shown below:

.ui-state-default .ui-icon {
    background-image: url("images/ui-icons_888888_256x240.png");
}
.ui-spinner .ui-icon {
    left: 0;
    margin-top: -8px;
    position: absolute;
    top: 50%;
}
.ui-icon-triangle-1-n {
    background-position: 0 -16px;
}

Therefore, to modify the position of .ui-icon-triangle-1-n (and -s), you can override their styling in your custom CSS.
