Emmet 網頁開發界的超跑
在這個速度的時代，網頁也擁有非常多加速開發的工具，例如今天要介紹的這個外掛「Emmet」，他支援的開發軟體也相當多，也就是不管腳踏車、機車還是房車，都可以裝上這個超跑的引擎，廢話不多說，先讓大家知道他如何節省網頁開發的時間，如果我們在網頁上要輸入以下的HTML結構：
<div>
<ul>
<li><a href="#">選項1</a></li>
<li><a href="#">選項2</a></li>
<li><a href="#">選項3</a></li>
<li><a href="#">選項4</a></li>
<li><a href="#">選項5</a></li>
<li><a href="#">選項6</a></li>
</ul>
</div>
在我們安裝好Emmet之後，僅需輸入以下的縮寫，再按下Tab鍵，即可以產生如上述般的HTML結構：
div>ul>li*6>a[#]{選項$}
仔細看看應該不難發現HTML標籤名稱的部分都在縮寫裡面，只是利用>來區隔每一層，如果要多個同樣的標籤可以用*後來輸入個數，標籤內的屬性值是利用[ ]來包住，{ }是標籤內的值。
是不是很神奇呀？趕快到Emmet的官方網頁下載或直接利用你的網頁編輯器來安裝這個外掛吧！
官方網站提到Emmet的特色有六點，分別是：
- HTML from CSS：如果你已經對CSS的選取器有概念，那就已經知道Emmet該如何去縮寫你的HTML代碼。
- Dynamic snippets：在使用縮寫的時候，只要稍微更動一些名稱，就可以得到截然不同的結果。
- Ultra-fast coding：快速的編寫模式，可以快速選取標籤、移動游標、產生上一層或下一層結構。
- Customizable：可以透過編輯JSON檔案來客製化一些程式碼。
- Platform for new tools：透過編輯開放的程式碼，可以產生新的使用模式。
- Highly portable：高度輕便可攜。
Emmet支援的網頁編輯器也非常多，如下圖所示：

A brief history of sunglasses, from Ancient Rome to Hollywood
kraken market
Sunglasses, or dark glasses, have always guarded against strong sunlight, but is there more to “shades” than we think?
The pupils of our eyes are delicate and react immediately to strong lights. Protecting them against light — even the brilliance reflected off snow — is important for everyone. Himalayan mountaineers wear goggles for this exact purpose.
Protection is partly the function of sunglasses. But dark or colored lens glasses have become fashion accessories and personal signature items. Think of the vast and famous collector of sunglasses Elton John, with his pink lensed heart-shaped extravaganzas and many others.
When did this interest in protecting the eyes begin, and at what point did dark glasses become a social statement as well as physical protection?
The Roman Emperor Nero is reported as holding polished gemstones to his eyes for sun protection as he watched fighting gladiators.
We know Canadian far north Copper Inuit and Alaskan Yupik wore snow goggles of many kinds made of antlers or whalebone and with tiny horizontal slits. Wearers looked through these and they were protected against the snow’s brilliant light when hunting. At the same time the very narrow eye holes helped them to focus on their prey.
In 12th-century China, judges wore sunglasses with smoked quartz lenses to hide their facial expressions — perhaps to retain their dignity or not convey emotions.

Carrie Underwood slated to perform at Trump’s inauguration
kraken зайти
Country music star Carrie Underwood is slated to perform “America the Beautiful” at President-elect Donald Trump’s inauguration, according to a copy of the program obtained by CNN and confirmed by a spokesperson for the inaugural committee.
“I love our country and am honored to have been asked to sing at the Inauguration and to be a small part of this historic event,” Underwood said in a statement to CNN. “I am humbled to answer the call at a time when we must all come together in the spirit of unity and looking to the future.”
The presidential oath of office will be administered by Supreme Court Chief Justice John Roberts with Justice Brett Kavanaugh expected to administer the oath of office to Vice President-elect JD Vance.
Trump’s inauguration as the 47th president of the United States will take place on January 20 at the US Capitol.
Underwood is a big get for Trump’s inauguration, considering Hollywood’s Trump blackout over the course of his political career.
In his first term and throughout the past three elections, Trump has struggled to garner support from major Hollywood stars. At the Republican National Convention last year, the two biggest stars onstage with Trump were musician Kid Rock and retired WWE wrestler Hulk Hogan – a far cry from a superstar at the height of their career, like Underwood.
The Grammy-winning artist is as high-profile as you can get in country music, not only with numerous platinum hits, but also with public-facing, mainstream business associations. Underwood is the face of Sunday Night Football and is set to make her debut this March as a judge on ABC’s “American Idol” – the singing competition show that catapulted her to fame when she won in 2005.
While many NFL fans will likely applaud Underwood for singing at the inauguration, any time a celebrity aligns themselves with Trump, they run the risk of alienating left-leaning fans and Hollywood allies.
Underwood has kept her politics under wraps over the course of her career. In her statement, she did not mention Trump by name and kept her focus on unifying the country – still, Underwood’s decision to publicly align with Trump is a big statement for any star, particularly one as private as the singer.
Historically, Hollywood has always been closely associated with the Democratic Party, but country stars have always been an outlier, leaning more conservative. In recent years, as new singers join the genre, country music has gotten to be more progressive. This past election cycle, country stars like Mickey Guyton and Maren Morris stood with Vice President Kamala Harris.
