Проверьте ваши навыки: Селекторы
================================

Цель этой задачи — помочь вам проверить ваше понимание селекторов в CSS.

**Примечание:** вы можете проверять решения в интерактивном редакторе, расположенном ниже, но, возможно, вам будут полезны онлайн-инструменты, такие как CodePen, jsFiddle или Glitch, которые можно использовать для работы над заданием, предварительно загрузив в них код.

Если вы зашли в тупик, обратитесь к нам за помощью — смотрите раздел Оценка или дальнейшая помощь внизу этой страницы.

Selectors One
-------------

Without changing the HTML, use CSS to do the following things:

* Make h1 headings blue.
* Give h2 headings a blue background and white text.
* Cause text wrapped in a span to have a font-size of 200%.

Selectors Two
-------------

Without changing the HTML, make the following changes to the look of the content in this example:

* Give the element with an id of `special` a yellow background.
* Give the element with a class of `alert` a 1px grey border.
* If the element with a class of `alert` also has a class of `stop`, make the background red.
* If the element with a class of `alert` also has a class of `go`, make the background green.

Selectors Three
---------------

In this example, try making the following changes without adding to the HTML.

* Style links, making the link-state orange, visited links green, and remove the underline on hover.
* Make the first element inside the container font-size: 150% and the first line of that element red.
* Stripe every other row in the table by selecting these rows and giving them a background color of #333 and foreground of white.

Selectors Four
--------------

In this task try the following:

* Make any paragraph that directly follows an h2 element red.
* Remove the bullets and add a 1px grey bottom border only to list items that are a direct child of the ul with a class of list.

Selectors Five
--------------

In this final task add CSS using attribute selectors to do the following:

* Target the `<a>` element with a `title` attribute and make the border pink (`border-color: pink`).
* Target the `<a>` element with an `href` attribute that contains the word `contact` somewhere in its value and make the border orange (`border-color: orange`).
* Target the `<a>` element with an `href` value starting with `https` and give it a green border (`border-color: green`).

Assessment or further help
--------------------------

You can practice these examples in the Interactive Editors mentioned above.

If you would like your work assessed, or are stuck and want to ask for help:

1. Put your work into an online shareable editor such as CodePen, jsFiddle, or Glitch. You can write the code yourself, or use the starting point files linked to in the above sections.
2. Write a post asking for assessment and/or help at the MDN Discourse forum Learning category. Your post should include:
    * A descriptive title such as "Assessment wanted for Selectors skill test 1".
    * Details of what you have already tried, and what you would like us to do, e.g. if you are stuck and need help, or want an assessment.
    * A link to the example you want to be assessed or need help with, in an online shareable editor (as mentioned in step 1 above). This is a good practice to get into — it's very hard to help someone with a coding problem if you can't see their code.
    * A link to the actual task or assessment page, so we can find the question you want help with.
