That's a wrap on our live coverage of this third convention night - thanks for joining us. Before we go, let's recap on some of the major moments:
We heard from Kamala Harris as she accepted her historic nomination as the second woman ever to be the Democratic Party's vice-presidential candidate.
With an emphasis on her biracial upbringing and family values, Harris positioned herself and Biden as leaders who could bring the change America needs at a time of racial division, economic hardship, virus-related challenges - and "failed leadership"
Former US President Barack Obama warned that the very future of American democracy is at stake in November's poll. In a scathing attack he said Donald Trump had treated the office like a reality show
For his part Trump hit back on Twitter saying Obama and Biden did not do a good job while in office, calling them ineffective and "terrible".

Thursday night is the final evening of the convention - culminating with Joe Biden's acceptance speech as the Democrats' presidential pick.
Mr Obama will be back, introducing his old White House partner. We'll also hear from the Biden family, Senators Cory Booker (an ex-rival for the nomination) and Tammy Duckworth (who was reportedly on the vice-presidential shortlist), and California Governor Gavin Newsom, among others.

Social media moments of the night
In a fast-paced evening at the Democratic National Convention, several moments sparked conversations that lit up social media.
When actress Kerry Washington, who hosted the third night of the all-virtual convention, mentioned learning about the US constitution in the 8th grade, she inspired a very personal reaction: from her teacher.
Former Congresswoman Gabby Giffords' powerful speech about her road to recovery after a gunman almost killed her, and her thoughts on the future of the US made a big impact.
And when former President Barack Obama’s attacked his successor, President Donald Trump, in an eviscerating speech, legions of Obama supporters took to Twitter, making "#MyPresident" one of the top trends.
Kamala
Harris' brief acceptance speech was like an elopement in place of a wedding.
Held in a makeshift stage in a Delaware hotel instead of the Wisconsin
Centre where the Democratic National Convention is supposed to be, the venue
provided six American flags and a podium for Harris, who had no audience
or energy to jazz up the moment. It came off as a speech written by an
efficiency expert- or worse, a committee of efficiency experts, who wanted to
check the boxes, and quickly.
There was
little policy discussion. Rather than talk at length about the coronavirus and
racism, Harris melded the two together "There is no vaccine for
racism," she said. And who can argue with that?
While running
mates are expected to be pit bulls against the opposition, Harris meekly cited
three things she didn't like about President Donald Trump --
“constant chaos,” “incompetence, and “callousness.” No one would argue. But
there was no sound bite destined to lead in news stories. No big rhetorical
moment. Everyone else already had said that Joe can bring the country together.
Harris is not
afraid to attack. She's not afraid to be blunt. I can only guess that she's trying
to do her job as the campaign wants her to do it. But the campaign is clueless.
And so the usually sharp Harris seemed so as well.

A simple guide to the election
After all the drama of day three of the Democratic convention, you might be looking for a refresher on what's going on with the US election - the wider picture, if you like. Here's the BBC's simple guide to candidates, campaigns and conventions.
KJ Kearney, a voter from South Carolina, tells BBC he would give Harris's speech eight out of 10.
He liked that she acknowledged her biracial background, links to her historical black college and sorority, and her family.
"I’m glad that she was very forthright about who she is and all the things that make her who she is.
"And she stood up for Joe—that’s her job and I think that’s what people are looking for her to be," Kearney, 37, said.
"In the next 76 days, they’re going to need for her to drive home the messages of the Democratic party and to help smooth those rough patches that Joe may have on the trail... But in terms of her first appearance as the Democratic VP nominee, I think she did a very good job."
Voters react: Kamala 'made her case'
BBCCopyright: BBC
Peyton Forte is a Democrat and a first-time voter. So far she hasn't been swayed by Kamala Harris.
"I think that we kind of get carried away by 'firsts', especially as black people, by the 'first this' and 'first that', it's just seen as a gigantic milestone," she told the BBC last week. "But are you fighting for some of the values that the black community holds dear?"
But the 21-year-old says she was moved by Harris's speech tonight.
"Kamala’s speech was particularly moving to me because she spent less time attacking President Trump and more time making her case as a leader under the Biden Administration. She exuded a confidence that made you feel as though she was speaking as the current vice-president," she says.
But Forte still isn't totally sold by the former prosecutor.
"If I had one critique, it’d be the part where she claimed that we could end this pandemic under the leadership of Joe Biden. Sure, his response to the coronavirus would likely be much better than the current administration’s. However, a change in leadership alone will not eliminate this pandemic."
'This was Harris's biggest moment'
Anthony Zurcher
BBC North America reporter
Kamala Harris has had turns in the limelight before, but tonight was her biggest moment so far.
The now-official 2020 Democratic vice-presidential nominee had a bit of an extra challenge, too, having to directly follow Obama, the party’s most beloved and rhetorically gifted politician.
What Harris offered was a bit of an amalgam – one that sometimes connected and occasionally plodded. It was part biographical introduction, part sales pitch for Biden and – most notably - part frontal attack on structural racism.
“There is no vaccine for racism,” she said in what will probably be her most quoted line. “We have got to do the work.”
Harris tried to cast her prosecutorial background as an advantage for a general election audience, speaking of how she always tries to fight for justice.
“I know a predator when I see one,” she said at one point, pausing long enough for her fellow Democrats to fill in the blanks.
Her speech was delivered with smiles and warmth, but took place in a rather haunting environment – a room constructed to replicate a party convention hall, but devoid of a cheering crowd.
Along with the vacant classrooms from which Senator Elizabeth Warren and Jill Biden spoke earlier, the atmospheres made it seem that the emptiness of the current pandemic-stricken nation is a feeling Democrats want to highlight – and lay at Donald Trump’s feet.
Looks like President Trump listened to Harris' speech too.
He's just tweeted a suggestion that Harris called her new running mate Biden a racist. But that isn't true.
Biden and Harris did clash over race issues during the second Democratic debate - but while she confronted him on his voting record, she also began by saying: "I do not believe you are a racist and I agree with you when you commit yourself to the importance of finding common ground."
You can watch their exchange in the clip below.

Video caption: Harris and Biden clash over his race recordHarris and Biden clash over his race record
Joe Biden has talked about himself as a transitional figure, he's flirted with the idea that he wouldn't run for a second term were he elected, so the choice of vice-president is all the more important.
Kamala Harris is in her mid-50s, she represents the future of the Democratic Party, the continuation of the Obama coalition, so the question is, will she be able to generate the same excitement on the ticket that Barack Obama did when he was leading in 2008 and 2012.
That's one of the reasons that Joe Biden has picked her,so that she can bring to the ticket the youthful vigour, the ability to turn out voters in huge numbers.
How does India view the Harris nomination?
Soutik Biswas
India Correspondent
Kamala Harris expectedly spoke about her biracial roots at the beginning of her 20-minute speech.
She said she stood on the “shoulders of my mother”, who came from India when she was 19 to study in the US, fell in love with a Jamaica-born student, and tirelessly raised her two children. She “raised us to be proud and strong black women and be proud of our Indian heritage”.
Ms Harris mostly reiterated what she has already said in her 2018 memoirs - her mother instilling values about the importance of the family, and her links with her extended family in India, including her uncle and an aunt who she calls “Chitti” or younger mother.
Indians have been mixed in their response to Ms Harris’s ticket.
Prime Minister Narendra Modi’s supporters are ambivalent, partly because of Ms Harris’s criticism of his move to revoke Kashmir’s autonomy, and the refusal of his foreign minister to meet a congresswoman who has been critical of the same move.
And although Indian-Americans have historically voted for Democrats for being immigration friendly, President Trump is considered a friend of India and Mr Modi.
It will be interesting to see how much support Ms Harris can garner from Indian American voters in these polarised times.
Harris calls for a fight with conviction, with hope and confidence.
"Years from now, this moment will have passed. And our children and our grandchildren will look in our eyes and ask us: Where were you when the stakes were so high? They will ask us, what was it like?"And we will tell them. We will tell them, not just how we felt. We will tell them what we did."
And that's a wrap for her speech accepting the vice-presidential nomination.
She's greeted with applause from a slew of teleconferencing screens - and to a socially distanced visit from her running mate, Joe Biden, and their spouses.

Harris says the new generations are pushing us to "live the values we share".
"Make no mistake, the road ahead will not be not easy," Harris says. "We will stumble. We may fall short. But I pledge to you that we will act boldly and deal with our challenges honestly."
She says that Americans are already standing for a better future, and in a contrast to her criticisms of Trump's lack of leadership, she praises the work of everyday Americans.
"We see it in the doctors, the nurses, the home health care workers and the frontline workers who are risking their lives to save people they’ve never met. We see it in the teachers and truck drivers, the factory workers and farmers, the postal workers and the poll workers, all putting their own safety on the line to help us get through this pandemic."
"And we see it in so many of you who are working, not just to get us through our current crises, but to somewhere better."She adds: "It's not about Joe or me. It's about you."
Harris: No vaccine for racism

Video caption: Kamala Harris: There is no vaccine for racismKamala Harris: There is no vaccine for racism
"Let's be clear: there is no vaccine for racism," Harris says. "For George Floyd. For Breonna Taylor. For the lives of too many others to name. For our children. For all of us."
Harris has been praised for her response to the anti-racism protests across the nation in recent weeks.
"We must elect a president who will bring something different, something better, and do the important work. A president who will bring all of us together—Black, White, Latino, Asian, Indigenous—to achieve the future we collectively want."
Harris attacks 'failure of leadership'
Harris says her mother probably could never have imagined that she would one day be standing here, and saying: "I accept your nomination for vice-president of the United States of America."
Harris says she does so committed to the same values she learned from her mother.
She describes the vision of America as a "beloved community, where all are welcome, no matter what we look like, no matter where we come from or who we love" - a vision, she says, that she shares with Joe Biden.
"A country where we may not agree on every detail, but we are united by the fundamental belief that every human being is of infinite worth."
Now, it's time to take on Trump.
"Donald Trump’s failure of leadership has cost lives and livelihoods," Harris says.
"We are a nation that is grieving - grieving the loss of life, the loss of jobs, a loss of certainty."
Harris: Family is my best friend

Harris says her mother taught her to put family first.
"The family you're born into, and the family you choose," she says. "Family is my husband Doug, who I met in a blind date set up by my best friend. Family is our beautiful children, Cole and Ella, who call me Momala. Family is my sister. Family is my best friend, my nieces and my godchildren. Family is my uncles, my aunts, and my chithis."
She says her mother was the most important person in her life, and her guidance has shaped Harris' life.
"At every step of the way I’ve been guided by the words I spoke that first time I was in a courtroom: Kamala Harris for the people."
Harris begins by talking about the generations of women who have worked "to make democracy and opportunity real".
"They paved the way for the trailblazing leadership of Barack Obama and Hillary Clinton, and these women inspired us to pick up the torch and fight on."
She says there's another woman too, whose shoulders she stands on: her mother's.
"[Shyamala Gopalan Harris] came here from India at age 19 to pursue her dream of curing cancer. At the University of California, she met my father, Donald Harris, who had come from Jamaica to study economics. They fell in love in that most American way - while marching together for justice in the civil rights movement of the 1960s."
Kamala Harris takes centre stageImage caption: Kamala Harris takes centre stage
Though she is speaking after party icon Barack Obama, Kamala Harris is arguably the real star of this evening. She's now on the stage to formally accept her role as Joe Biden's vice-presidential running mate.
Obama to young voters: You give our democracy new meaning
Obama addresses the young Americans who have taken to the streets across the US to protest police brutality this summer.
"To the young people who led us this summer, telling us we need to be better – in so many ways, you are this country’s dreams fulfilled," he says. "Earlier generations had to be persuaded that everyone has equal worth. For you, it’s a given – a conviction."
"You can give our democracy new meaning. You can take it to a better place. You’re the missing ingredient – the ones who will decide whether or not America becomes the country that fully lives up to its creed."
So with 76 days until election day, what's next?
"Voting like never before," he says.
Obama calls out Trump 'enablers'

Video caption: Barack Obama: Trump doesn't take his job seriouslyBarack Obama: Trump doesn't take his job seriously
The blows between presidents keep coming. We've just had the Trump response on Twitter to President Obama's remarks, but they are not over yet. In this election, Obama says, America's democracy is at stake.
"The right to vote is sacred," he says, "And we should be making it easier for people to cast their ballot, not harder."
"None of this should be controversial. These shouldn’t be Republican principles or Democratic principles. They’re American principles. But at this moment, this president and those who enable him, have shown they don’t believe in these things."
Echoing his wife - former First Lady Michelle Obama who spoke on Monday night - President Obama then urges Americans to vote.
"This president and those in power – those who benefit from keeping things the way they are – they are counting on your cynicism. They know they can’t win you over with their policies," he says. "So they’re hoping to make it as hard as possible for you to vote, and to convince you that your vote doesn’t matter. That’s how they win."
Trump's tuned into Obama
The sitting US President has tuned into his predecessor's address - and it doesn't sound like he's happy.
Trump has tweeted about an accusation he's levied before at Obama: that the Democrat spied on his campaign.
But there's no evidence of any such covert operation and Trump, though he's called it treasonous, hasn't offered any of his own evidence about the matter.

But there's no evidence of any such covert operation and Trump, though he's called it treasonous, hasn't offered any of his own evidence about the matter.
Trump also - continuing to use all caps - asked why Obama didn't endorse his vice-president earlier on.
