# --description--

Kabla ya kufika mbali sana katika mtindo wako, unapaswa kutumia darasa la `sr-only`. Unaweza kutumia CSS kutengeneza vipengee vilivyo na darasa hili kufichwa kabisa kutoka kwa ukurasa unaoonekana, lakini bado vitangazwe na visoma skrini.

CSS unayokaribia kuandika ni seti ya kawaida ya sifa zinazotumiwa kuhakikisha vipengele vimefichwa kabisa kimwonekano.

Kichaguzi cha `span[class~="sr-only"]` kitachagua kipengele chochote cha `span` ambacho `class` *inajumuisha* `sr-only`. Unda kichaguzi hicho na ukipe sifa ya `border` iliyowekwa kuwa `0`.

# --hints--

Unapaswa kuwa na kichaguzi cha `span[class~="sr-only"]`.

```js
assert(new __helpers.CSSHelp(document).getStyle('span[class~="sr-only"]'));
```

Kichaguzi chako cha `span[class~="sr-only"]` kinafaa kuwa na sifa ya `border` iliyowekwa kuwa `0`.

```js
assert(new __helpers.CSSHelp(document).getStyle('span[class~="sr-only"]')?.getPropertyValue('border-width') === '0px');
```
