# --description--
|
||||
|
||||
In this lab, you will practice the different styles that can be applied to links when they are hovered over, focused, clicked, and visited.
|
||||
|
||||
**Objective:** Fulfill the user stories below and get all the tests to pass to complete the lab.
|
||||
|
||||
**User Stories:**
|
||||
|
||||
1. You should have an unordered list with the class `todo-list`.
|
||||
2. Inside the unordered list, you should have four list items.
|
||||
3. Inside each list item, there should be:
|
||||
|
||||
- An `input` element with the type `checkbox` and `id` set to a unique value.
|
||||
- A `label` element with the `for` attribute set to the corresponding `input` element's `id`.
|
||||
- An unordered list with the class `sub-item`.
|
||||
- A list item with an anchor element in it. The anchor should have the class `sub-item-link`, a valid `href` value, and a `target` value that makes the link open in a new tab.
|
||||
|
||||
4. You should remove the default list style from your `.todo-list`.
|
||||
5. Your anchor elements shouldn't have any default text decoration.
|
||||
6. You should set the text color of the links to a color of your choice.
|
||||
7. When your links are visited, the color should change to another color of your choice.
|
||||
8. When your links are hovered over, the color should change to another color of your choice.
|
||||
9. When your links are focused, there should be a colored outline around the link.
|
||||
10. When your links are clicked, the color should change to another color of your choice.
|
||||
|
||||
**Note:** Be sure to link your stylesheet in your HTML and apply your CSS.
|
||||
|
||||
# --hints--
|
||||
|
||||
You should have an unordered list with the class `todo-list`.
|
||||
|
||||
```js
|
||||
assert.exists(document.querySelector('.todo-list'));
|
||||
```
|
||||
|
||||
You should remove the default list style from your `.todo-list`.
|
||||
|
||||
```js
|
||||
assert(new __helpers.CSSHelp(document).getStyle('.todo-list')?.listStyleType === 'none' || new __helpers.CSSHelp(document).getStyle('.todo-list')?.listStyle === 'none');
|
||||
```
|
||||
|
||||
You should have four list items inside the unordered list.
|
||||
|
||||
```js
|
||||
const li = document.querySelectorAll('.todo-list li');
|
||||
assert.strictEqual(li.length, 8);
|
||||
```
|
||||
|
||||
Each list item should contain an `input` element with the type `checkbox`.
|
||||
|
||||
```js
|
||||
const checkboxes = document.querySelectorAll('.todo-list li input[type="checkbox"]');
|
||||
assert.strictEqual(checkboxes.length, 4);
|
||||
```
|
||||
|
||||
All of the `input` elements should have an `id`.
|
||||
|
||||
```js
|
||||
const inputs = document.querySelectorAll('input');
|
||||
assert(!!inputs.length);
|
||||
for (let input of inputs) {
|
||||
assert.isAbove(input?.id.length, 0);
|
||||
}
|
||||
```
|
||||
|
||||
After the `label` elements, there should be an unordered list with the class `sub-item`.
|
||||
|
||||
```js
|
||||
const labelSbItems = document.querySelectorAll('label+ul.sub-item');
|
||||
assert.equal(labelSbItems.length, 4);
|
||||
```
|
||||
|
||||
The `li` inside the `ul` with the class `sub-item` should have an anchor element with the class `sub-item-link`.
|
||||
|
||||
```js
|
||||
const allItems = document.querySelectorAll('label + ul.sub-item li a.sub-item-link');
|
||||
assert.equal(allItems.length, 4);
|
||||
```
|
||||
|
||||
All of the anchor elements should have a valid `href`.
|
||||
|
||||
```js
|
||||
const links = document.querySelectorAll('a');
|
||||
assert(!!links.length);
|
||||
for (let link of links) {
|
||||
assert.isAbove(link.href.length, 0);
|
||||
}
|
||||
```
|
||||
|
||||
All of the `anchor` elements should have a text.
|
||||
|
||||
```js
|
||||
const links = document.querySelectorAll('a');
|
||||
assert(!!links.length);
|
||||
for (let link of links) {
|
||||
assert.isAbove(link.innerText.length, 0);
|
||||
}
|
||||
```
|
||||
|
||||
All of the `label` elements should have a `for` attribute.
|
||||
|
||||
```js
|
||||
const labels = document.querySelectorAll('label');
|
||||
assert(!!labels.length);
|
||||
for (let label of labels) {
|
||||
assert.isAbove(label.htmlFor.length, 0);
|
||||
}
|
||||
```
|
||||
|
||||
All of the `label` elements should have some text.
|
||||
|
||||
```js
|
||||
const labels = document.querySelectorAll('label');
|
||||
assert(!!labels.length);
|
||||
for (let label of labels) {
|
||||
assert.isAbove(label.innerText.length, 0);
|
||||
}
|
||||
```
|
||||
|
||||
Each `a` element should have a `target` attribute with the value of `_blank`.
|
||||
|
||||
```js
|
||||
const anchors = document.querySelectorAll('a');
|
||||
assert(!!anchors.length);
|
||||
for (let anchor of anchors) {
|
||||
assert.equal(anchor.target, '_blank');
|
||||
}
|
||||
```
|
||||
|
||||
The links on the page should have no underline by default.
|
||||
|
||||
```js
|
||||
assert(new __helpers.CSSHelp(document).getStyle('a.sub-item-link')?.textDecoration === 'none' || new __helpers.CSSHelp(document).getStyle('a')?.textDecoration === 'none' || new __helpers.CSSHelp(document).getStyle('.sub-item-link')?.textDecoration === 'none' );
|
||||
|
||||
```
|
||||
|
||||
The links should change color when hovered over.
|
||||
|
||||
```js
|
||||
assert(new __helpers.CSSHelp(document).getStyle('.sub-item-link:hover')?.color || new __helpers.CSSHelp(document).getStyle('a:hover')?.color || new __helpers.CSSHelp(document).getStyle('a.sub-item-link:hover')?.color);
|
||||
```
|
||||
|
||||
The links should change color when they are being clicked.
|
||||
|
||||
```js
|
||||
assert(new __helpers.CSSHelp(document).getStyle('.sub-item-link:active')?.color || new __helpers.CSSHelp(document).getStyle('a:active')?.color || new __helpers.CSSHelp(document).getStyle('a.sub-item-link:active')?.color);
|
||||
```
|
||||
|
||||
The links should have an outline when focused.
|
||||
|
||||
```js
|
||||
assert(new __helpers.CSSHelp(document).getStyle('.sub-item-link:focus')?.outline || new __helpers.CSSHelp(document).getStyle('a:focus')?.outline || new __helpers.CSSHelp(document).getStyle('a.sub-item-link:focus')?.outline);
|
||||
|
||||
```
|
||||
|
||||
The links should change color once visited.
|
||||
|
||||
```js
|
||||
assert(new __helpers.CSSHelp(document).getStyle('.sub-item-link:visited')?.color || new __helpers.CSSHelp(document).getStyle('a:visited')?.color || new __helpers.CSSHelp(document).getStyle('a.sub-item-link:visited')?.color);
|
||||
|
||||
```
