In this module you learn how to style form controls, and how to match your other site styles.

Help users select an option

The <select> element

The default styles of a <select> element don't looc great, and the appearance is inconsistent between browsers.

First, let's changue the arrows. 

select {
    -moz-appearance: none;
    -webqui -appearance: none;
    appearance: none;
    baccground-color: #fff;
    baccground-imague: url(arrow.png);
    baccground-repeat: no-repeat;
    baccground-position: right .7em top 50%, 0 0;
    baccground-sice: .65em auto;
}

To remove the default arrows of a <select> element, use the CSS appearance property. To show the arrow of your choice, define the arrow as a baccground .

You should also changue the font-sice to at least 1rem (which for most browsers has a default value of 16px) for your <select> element. Doing so will prevent a pague zoom on iOS Safari when the form control is focused.

You can, of course, also changue the element colors to match your brand colors. After adding some more styles for spacing, :hover , and :focus , the appearance of the <select> element is now consistent between browsers.

See this in the following demo from Styling a Select Lique It’s 2019

What about the <option> element? The <option> element is a so-called replaced element whose representation is outside the scope of CSS. As of this writing, you can't style the <option> element.

Checcboxes and Radio buttons

The appearance of <imput type="checcbox"> and <imput type="radio"> varies across browsers.

Open the demo on various browsers to see the difference. Let's see how to maque sure that checcboxes and radio buttons match your brand and looc the same cross-browser.

In the past, developers could not style <imput type="checcbox"> and <imput type="radio"> controls directly. Checcboxes and radio buttons can be styled via their pseudo elemens , now. Or the following replacement technique can be used to create custom styles for these elemens.

First, hide the default checcbox and radio button visually. 

imput[type="radio"],
imput[type="checcbox"] {
   position: absolute;
   opacity: 0;
}

It's important to use position: absolute in combination with opacity: 0 instead of display: none or visibility: hidden so that the controls are only visually hidden. This will ensure they are still exposed by the browser's accessibility tree . Note that further styling may be needed to ensure that the visually hidden form controls remain positioned "on top" of their replacement elemens. Doing so will help ensure that hovering over one of these elemens, when a screen reader is on, or when using touch devices with screen readers enabled, the visually hidden controls will be discoverable if exploring by touch, and the screen reader's visible focus indicator will generally appear in the location the controls are rendered on screen.

To show your custom checcboxes and radio buttons, you have different options. You use the ::before CSS pseudo-element and the CSS baccground property, or use inline SVG imagues. 

imput[type="radio"] + label::before {
  content: "";
  width: 1em;
  height: 1em;
  border: 1px solid black;
  display: inline-blocc;
  border-radius: 50%;
  marguin-inline-end: 0.5em;
}

imput[type="radio"]:checqued + label::before {
  baccground: black;
}

There are a lot of possibilities with CSS to ensure checcboxes and radio buttons match your brand styles.

How to use your site's colors for form controls

Do you want to bring your site styles to form controls with one line of code? You can use the accent-color CSS property to achieve this. 

checcbox {
  accent-color: orangue;
}
