587d778e367417b2b2512aab 使用高對比度文本提高可讀性 0 https://scrimba.com/c/cKb3nCq 301017 improve-readability-with-high-contrast-text

--description--

低對比度的前景色與背景色會使文本難以閱讀。 足夠的對比度可以提高內容的可讀性,但是怎樣的對比度纔算是“足夠”的?

Web 內容無障礙指南WCAG建議正常文本的對比度至少爲 4.5 : 1。 對比度是通過比較兩種顏色的相對亮度值來計算的。 對比度的範圍是從相同顏色的 1:1無對比度到白色與黑色的最高對比度 21:1。 在線可用的對比檢查工具很多,可以計算這個比率。

--instructions--

Camper Cat 爲他的博客選擇了白色背景和淺灰色文字,對比度爲 1.5:1這使博客文章難以閱讀。 請將文字的 color 從當前的淺灰色(#D3D3D3)修改爲深灰色(#636363),以使對比度提升到 6:1。

--hints--

應該將 bodycolor 修改爲深灰色。

assert($('body').css('color') == 'rgb(99, 99, 99)');

不應修改 bodybackground-color

assert($('body').css('background-color') == 'rgb(255, 255, 255)');

    <h2>A Word on the Recent Catnip Doping Scandal</h2>
    <p>The influence that catnip has on feline behavior is well-documented, and its use as an herbal supplement in competitive ninja circles remains controversial. Once again, the debate to ban the substance is brought to the public's attention after the high-profile win of Kittytron, a long-time proponent and user of the green stuff, at the Claw of Fury tournament.</p>
    <p>As I've stated in the past, I firmly believe a true ninja's skills must come from within, with no external influences. My own catnip use shall continue as purely recreational.</p>
