这是我的菜鸟问题，但是，为什么我定位的导航周围有白色间距？我创建了一个出现在移动设备底部的导航，我的导航元素中有看起来像顶部和底部填充的内容，但是当我拉在开发工具上没有填充或任何我认为会导致这种情况的东西，它是什么以及如何删除它？

Somalia (/səˈmɑːliə, soʊ-, -ljə/ so-mah-lee-ə; Somali: Soomaaliya; Arabic: الصومال aṣ-Ṣūmāl),
officially the Federal Republic of Somalia[1] (Somali: Jamhuuriyadda Federaalka Soomaaliya, Arabic:
<bdi>جمهورية الصومال الفيدرالية</bdi> Jumhūrīyat aṣ-Ṣūmāl al-Fidirālīyah), is a country located in the
Horn of Africa. It is bordered by Ethiopia to the west, Djibouti to the northwest, the Gulf of Aden to the
north, the Indian Ocean to the east, and Kenya to the southwest. Somalia has the longest coastline on
Africa's mainland, and its terrain consists mainly of plateaus, plains and highlands. Climatically, hot
conditions prevail year-round, with periodic monsoon winds and irregular rainfall.
</p>
<p>Somalia has an estimated population of around 12.3 million. Around 85% of its residents are ethnic
Somalis,[3] who have historically inhabited the northern part of the country. Ethnic minorities are largely
concentrated in the southern regions. The official languages of Somalia are Somali and Arabic, both of
which belong to the Afroasiatic family. Most people in the country are Muslim, with the majority being Sunni.
</p>
<p>In antiquity, Somalia was an important commercial centre. It is among the most probable locations of the
fabled ancient Land of Punt. During the Middle Ages, several powerful Somali empires dominated the regional
trade, including the Ajuran Empire, the Adal Sultanate, the Warsangali Sultanate, and the Geledi Sultanate.
In the late 19th century, through a succession of treaties with these kingdoms, the British and Italian
empires gained control of parts of the coast and established the colonies of British Somaliland and Italian
Somaliland.[19][20] In the interior, Mohammed Abdullah Hassan's Dervish State repelled the British Empire
four times and forced it to retreat to the coastal region, before succumbing to defeat in 1920 by British
airpower.[22] The toponym Somalia was coined by the Italian explorer Luigi Robecchi Bricchetti (1855–1926).
Italy acquired full control of the northeastern, central and southern parts of the area after successfully
waging the so-called Campaign of the Sultanates against the ruling Majeerteen Sultanate and Sultanate of
Hobyo.[20] Italian occupation lasted until 1941, yielding to British military administration. British
Somaliland would remain a protectorate, while Italian Somaliland in 1949 became a United Nations
Trusteeship under Italian administration, the Trust Territory of Somaliland. In 1960, the two regions
united to form the independent Somali Republic under a civilian government.</p>
<p>The Supreme Revolutionary Council seized power in 1969 and established the Somali Democratic Republic.
Led by Mohamed Siad Barre, this government later collapsed in 1991 as the Somali Civil War broke out.
Various armed factions began competing for influence in the power vacuum, particularly in the south.
During this period, due to the absence of a central government, Somalia was a "failed state", and residents
returned to customary and religious law in most regions. A few autonomous regions, including the
Somaliland and Puntland administrations emerged in the north. The early 2000s saw the creation of fledgling
interim federal administrations. The Transitional National Government (TNG) was established in 2000,
followed by the formation of the Transitional Federal Government (TFG) in 2004, which reestablished
national institutions such as the military. In 2006, the TFG, assisted by Ethiopian troops,
assumed control of most of the nation's southern conflict zones from the newly formed Islamic Courts Union
(ICU). The ICU subsequently splintered into more radical groups such as Al-Shabaab, which battled the TFG
and its AMISOM allies for control of the region.</p>
<p>By mid-2012, the insurgents had lost most of the territory that they had seized. In 2011–2012, a
political process providing benchmarks for the establishment of permanent democratic institutions was
launched. Within this administrative framework a new provisional constitution was passed in August 2012,
which reformed Somalia as a federation.[29] Following the end of the TFG's interim mandate the same month,
the Federal Government of Somalia, the first permanent central government in the country since the start
of the civil war, was formed[30] and a period of reconstruction began in Mogadishu. Somalia has maintained
an informal economy, mainly based on livestock, remittances from Somalis working abroad, and
telecommunications</p>
